I think Paul does a fairly decent job of explaining here. At least he states that it is not as important as many think, but can be important depending on situation. Also, one doesn't need to spend $10k on a PS Audio power unit or any power unit in that range. On the flip side I have never seen power units at Walmart and would not purchase anything from there anyway. I never needed anything like a power conditioner until I moved into this one place that had sketchy power. I went and got a Panamax power conditioner/protector (expensive to me, but not nearly as much as a PS Audio power unit), but it solved a list of problems and saved my gear a couple of times and it is still doing it's job. If one doesn't have measurable sketchy power in their place, then it is not likely things like power conditioners are needed. Always a good idea to have a good surge protector though.
As always with PS Audio stuff it would lovely to have; But Paul's point that it is the verry crests of the voltage peaks being 'Cropped' as your most likely disadvantage caused by using a power conditioner I frankly doubt will be a problem with a{£30] 1000w conditioner with surge protection etc running little more than a hifi system.
I once had a situation where l had a power surge that took out a VCR. The power company did a chart on my line for 3 days and found spikes. They discovered over the years that 5 houses were on the same transformer, this by itself back in the early day wasn't to bad but home owners added to their homes. New AC pools new kitchens etc. But didn't tell the power co. This caused overloading. Finally l recieved the power surge and spike. The remedy Give me my own 25kva transformer. Suddenly Clean voltage amperage and more! No more problems and great audio/video! Yippie!
Thanks for the explanation on lowering the impedance, as it impacts the sound. Also the rolling off of the sine wave. These two items explain why I got better sound when I replaced my cheap .75 wall socket for an Audiophile Grade (better than Hospital Grade) wall socket. And when I included a linear filter on the power line. That linear filter actively keeps the impedance low at .05 Ohms. The socket, creates far better conductivity to the live power wires in the house. As it turns out, those cheap Home-Depot special power outlets have no copper behind them and the plugs themselves are loose and do not make cold welds against the power plug. Hospital Grade does have some copper behind it, for better and more reliable conductivity and has tighter plugs to make a cold weld against your Positive/Negative/Ground connector.
7:41 Kind of rhetorical question, does it matters if the AC power going into the power regulator comes from the golden 'audio grade' power cable that costs $600 or regular power cable that costs $10?
That's what your amps transformer does, it lowers the impedance to a specific setting in Ohms of power coming into the amp. You don't need a high-end clean power component in most major cities when one has a good transformer built into your amp. Every high- end audio company will list the transformers filtered amp impedance in terms of THD (Total Harmonic Distortion). What one really needs is a high quality surge protector. Save your money and invest in four of the most important products of any high- end system. 1) A great recorded musical source 2) A well built amp with a large high quality transformer. 3) A high-quality surge protector. 4) High quality efficient speakers that match the Ohm setting of amp. Then add roughly 20% of total cost of system on cables. Look into companies like Acoustic Zen, and AudioQuest for cables, just my opinion.
There's really simple phenomenons regarding power supply: noise (which is typically rejected by the transformer itself or the input common mode filter or PFC of SMPS), having enough power reserve in the bulk capacitors for transient power requirements of the amplifier and bus pumping. If an amplifier runs out of power, distortion is pretty bad, so there's no magic here.
These units are basically a double conversion topology UPS unit missing the battery backup. Yes they do re-generate clean low distortion AC to spite noisy or distorted input AC power. The question is if typical residential AC power is so bad that these units can make improvements in the reproduced audio. In most cases I don't think so. While some areas of the country do have bad power, the average home is more than good enough for fine audio reproduction. 3% to even 10% distortion on the incoming AC waveform will not compromise any competently designed linear or switch mode power supply, especially a switch mode power supply. The AC is rectified, what difference does some distortion make provided it does not change the RMS value significantly? Distortion on the input AC does not translate to amplifier output distortion. Now that is not being claimed directly but I think it's being assumed by non-technical customers. Another thing to keep in mind here, the Power Plant is still plugged into the so called dirty AC power. While I do believe it does produce a low impedance output, let's ask for how long? The PS Power plant can maintain this low output impedance only as long as it's internal power supply reserves hold up. Now does it hold up long enough to ride through average music transients? We don't know but that can certainly be tested. I would be interesting to run some tests comparing the amplifier DC rails against an audio clip on a quad trace storage scope with and without the PS Power Plant. I expect there will be some difference but then we have to quantify that to the performance of the amplifier circuit.
How would these PS-afficionados respond once they realize that the output stage of the Powerplant is actually eerily similar to a, ever loathed, Class D amp... ;-)
I understand it's easy to dismiss this because it doesn't quite fit your view but you might try giving these newer ideas and concepts a try. I've done my best in the short period of time I have to explain AC flat topping and the importance of refilling the missing energy as well as regulation. One thing to try and remember is that most power amplifiers have unregulated supplies and these are impacted even more by producing a distortion free sine wave. The only reason we measure (and provide an analyzer on the front panel) is to show the effects of clipping the AC waveform which, as I am sure you understand, happens when enough low power factor products on a shared line draw current at the peak of the sine wave. Lastly, this is only like a UPS in a distant way. A double conversion UPS, while functionally the same, is not the same. That's because UPS regenerators are class D amplifiers and they cannot deliver high amounts of peak current. This means that when they try and power low power factor devices they can actually make the power worse, often as high as 10% to 15% in the form of a divot in the sine wave at its peak.
PS Audio UPS's indeed regenerate their power from batteries that are (arguebly) slower to respond to fast changes. However, Class D amps, or frequency inverters which are in essence very similar, generate their power from high storage capacitors, that are very fast to respond and can handle transients perfectly fine. So I don't quite get your point.
Class D amplifier, in the way they are implemented in double conversion regenerators cannot deliver peak current. They do fine when the power factor is 1 (where voltage and current track each other) but when it begins to dip below 0.7 they cannot keep up. If you're really curious you can easily test it. We use a 500 watt variable power factor load and test all sort of devices. Nearly all fail. The problem is these peak currents can often time exceed 60 amps right at the peak of the sine wave. When we design and build a regenerator it has to handle these peaks. To do that requires enormous banks for power supply capacitors and very tough transistors. That's a lot of peak current.
PS Audio There's something seriously wrong with the design, when an household appliance's power factor dips below 0.7 Anyway, in the mills where I work as an electrical engineer, we power motors of several 100's of kilowatts in a similar way, to how a Class D amps functions. These motors do not cringe and when in normal operating mode, they usually don't fall below a power factor of 0.85. It's all a matter of size. When the converter can't keep up... it's too small... Replace it with a bigger one.
I have a tube guitar amp, the question is if i am better with just a extension of 230V with surge protection on my 16A eletricity socket on the wall or a APC UPS with 1400VA and 700w 230V with a pseudo sinewave? Or both? The tube amp only have 25w, and consumes 100/115w in full power. I will connect a Line6 HX Stomp and a CryBaby wah pedals in the FX Loop circuit in the amp. I live on Europe, Portugal to be precise. My house have 30+ years, should i check my circuit breaker for better ground? I have a circuit breaker that the only thing it controls is the suply of energy to that 16A eletricity socket. In the future i will buy a Furman but meanwhile i just want to know what is the best choise in my case. Thanks in advance. I know 0 about eletricity. I will loose dynamics with the UPS? More than with just the extension?
I am getting random popping coming from my def tech 6080 towers even with everything turned off but the towers plugged in the wall. could the built-in amps have issues? bought in 2009.
I'm late on this tutorial. Great topic and my brother (In the 70's Nippon engineer) was passionate about this. He built for me, a solution for the trash that the 'power' companies sell us ( eh showed me the proof). He said Audio/amps/refrigerators etc., are engineered for a correct fuel/power. You are correct on this, I've noticed most audio businesses do not push these benefits. Today my entire home has this benefit. (My 74 Sansui is still pushing it. NO repairs) Thanks brother...
Amen brother .. I constantly tell people that the only way to get true. full , dynamic sound from your refrigerator is to get rid of the trash that the 'power' companies sell us and use a 60hz-60hz rotary phase converter. When you run a fridge off straight wall power you loose all the bass.
Hi, We use a cheap generator to power our music gear. Guitar amps, P.A etc. Could the power it produces be damaging our equipment? Do we need to put a power conditioner or surge protector or something between the generator and our gear?
Paul P. Well, my point is correct. If you assume that my indirect point is that clean power often isn’t a relevant issue for most consumers and sold as snake oil a bit too much, you are right. Modern consumer electronics has build-in mains filters and power supplies intended to keep mains noise away from amp circuits. If your amp doesn’t have Vcc ripple or other noise measurable originating from the mains noise, you are fine. Electric noise is 100% measurable.
Very informative. With a transformer-rectifier-capacitor supply the impedance of the mains really comes into play when the diodes conduct on the peaks to keep the capacitors charged. So you listen to a combination of mains (inc transformer) and capacitor impedance and rectification quality. I have used transformer-rectifier-choke-capacitor supplies to good effect to eliminate the short conduction spikes. I guess without using synchronous rectification which will inevitably demand a move to switch mode supplies, this interaction with the mains will always remain. Switchmode technology has made big advances and one could always use decent amount of capacitors after the SMPS. It is already used succesfully in your power regenerator.
What’s the best option for clean power spending less then 1000 dollars. I use isolation Transformer system for cleaning the power to my Hifi system and it makes everything sound better than whiteout it I have two one small 100w isolation transformer that I use for Preamp and cd player and one big isolation transformer 1000w that I only use for small power amp Rotel 960BX 300w in effect and the power amplifier also sound better than whiteout it. I have also tried Isotek the plug shunt filter but my Hifi system sounds much better whit the isolation transformers. Totally isolating and regeneration of the power can be done whit a UPS 3000w system using caps and battery to store power but the UPS uninterrupted power system have to be built for Audio use. One other option is battery power and True sine wave 3000w inverter. It,s going to totally isolate power from the grid but the quality of the power output is going to be down to how good the inverter is to recreate 12v DC power to 230V 50-HZ sine wave power.
*I have a couple of Mr Tice's power blocks, makes a big difference - previous home I had added an isolation transformer on a sub-panel with 12ga wiring to the outlets all together made a HUGE difference*
Snake oil. Spend the extra money on a better pair of speakers or power amp or both. No power conditioner/regenerator can help a power amp with lousy power supply circuits inside the amp. If it is your house, pull a heavy cable from the breaker box to just power the system, that will do a lot more good and a whole lot cheaper.
I have owned a P10 since 2016 - very happy with it - powers a pair of 300 watt tube monoblocks., Listened to it with the Australian distributor, who describes music played through it as "sounding more organic" compared to a voltage correction device (Thor PS-10) which didn't condition the power amplifiers.
May be a dumb question: why not use a battery based generator like ecoflow? I am not listening to music all day, at least not at that level. So I am ok with the batteries only lasting a few hours. How good needs the inverter in such a solution to be to get „clean“ power? i still have the influence between the different music components. Is earthing a problem?
I'm no expert on the subject but this really makes little sense to me. I highly doubt that in a blind test one would ear the difference when using regular power and "clean power". I bet that the placebo effect and the sense of ownership of very expensive gear will make one think that the sound is better. If by any means a piece of equipment "messes" with the signal I would say it would be for the worse and not for the better.
Power conditioners absolutely make a sonic difference. The difference will not necessarily slap you in the face. But while listening with clean power, you will unexpectedly find yourself in "the zone". The real reality check will be after you have been listening with clean power for a while. Then, remove your power conditioner, and your music will lose its magic. It will sound more two dimensional and congested. Please note that: 1) no power conditioner, at any price, will make a difference on a $99 stereo purchased from Walmart. You need to have a good stereo, proper speaker placement, etc, in order to reap the benefits of clean power. 2) not all power conditioners help. Some will make your music sound worse. I have listened to products from Shunyata Research and Audioquest. Both make a beautiful improvement, with no downside. I would give Audioquest the edge. PS Audio's power products might also be very good. I never auditioned them. Cheers!
I dont know, I was sceptical, but after listening to Paul; the points do at least make sense from an electronic engineering perspective; but only on equipment that uses switch mode power supplies, it wont really improve a standard linear supply; because linears have large capacitor values with lots of stored energy anyway.
Any expensive equipment you buy makes you hear the difference, trust me!... You can clearly hear your SO yelling at you for wasting money on pointless crap!
I heard someone say you can get bad power if you use a surge suppressor strip. And suggested to plug it directly into the wall. But here in Florida would be disaster with all the storms.
I am hearing from some audiophiles that by using power conditioners, you are loosing dynamics from your system. Which is why I ditched mine for the wall plug.
A power conditioner on the AC side should have NO EFFECT on the dynamics of your audio signal. The ONLY reason a power conditioner might be desired is if your local power is subject to frequent brownouts or dips. Otherwise the amplifier itself should have a well designed power supply and have no requirement for a conditioner at all.
I always doubted this until I heard a DAC sound better with external power supply. Suddenly, as a novice audiophile, I can see why clean power makes a difference.
Seeing as every amplifier on the market runs on DC internally and has a fairly decent filtering circuit after rectification (filter caps, coil chokes/inductors, hell even internodal resistors), I posit that the design of the power supply is the important factor here - NOT the AC mains itself. As long as the AC is reasonably low noise, which it almost always is unless you have something else on that circuit misbehaving (cheap crappy computer power supplies, for example, often can throw tons of noise back into the mains lines), it doesn't matter. As far as voltage sag - that's not a problem, unless you have a wildly under-spec power supply, or for some inexplicable reason you're using vacuum tube rectifiers.
I would say that the average American home that had a pretty good stereo system would also have things plugged-in on various circuits that create noise in both the power and electromagnetic realms.
I am a recording engineer with a very keen ear for frequencies, I can hear difference when mixing between .1 db and 0.2 db, to me it's possible to hear that, so I am not going to say I am like the rest of people. BUT I am not chasing perfection of sound signal, but recently I have encountered something that I cannot forego, I started having constant clipping sound in my speakers. I thought it was the amount of buffer from my recording equipment, even when listening to RUclips or playing games. Then I started getting clicks and pops when AC unit came on much more severely, and I realized that clean power is an issue for me. I recently bought Voltage Regulator from Furman and will do further testing. I understand some chase some glorious "Holy Grail" of sound like Detective Monk, and usually never find it. Me on the other hand, I try to have an easy listening experience without clicks, pops, or buzzing in my speakers, that gets really painful when you are tired or pissed off about life, and you got this gnat in your ear going BZZZZ *CLICK-CLICK-CLICK-CLICK-CLICK* Some don't even hear it, so why would it bother them?
Over the years, I experimented with an array of power conditioners, filters, ups/battery backups, surge protectors, isolation transformers, etc. One problem that none of the power conditioning units I tried could fix was mechanical noise from the power transformers in all of my audio gear. These noises came and went. (My wife had a hairdryer that was a huge cause of this problem.) I finally tried a PS Audio Humbuster. Poof! The noises were gone, never to return.
I bought a $60.00 power conditioner to use with the PS. Sprout and B&W 602's. And WOW!!!! I love my Sprout even more. I can't afford the expensive gear gut I hear the difference already. It's not my imagination , it's real.
I disagree. After hearing the Isotek Aquarius in Oslo HiFi Center on some KEF floor standing speakers and a Rotel integrated amplifier i could really hear a significant difference. Especially in the bass area. I switched back and forth between ordinary cables and Isotek's own power cables and the Aquarius. The result was the same every time. Better sound without losning any dynamics. My brother was there also and he just nodded his head and said the same.
Sir, what if we use switch mode power supply to an amplifier? I've seen lot of home audio system manufacturers like sony, jbl and Harman kardon systems use much better smps units nowadays
Fun story on this subject. One computer installation I saw in an industrial location that was experiencing extremely bad mains power. So they used a crazy device that is both simple and muscular. So, three parts of it. First a motor, and a big one. Lets say something like a motor that runs a pump for a swimming pool. Second a generator. You turn the shaft on the generator at 60rpm and it generates 115vac. It’s gonna be big generator. Connect the motor to the generator with a shaft. OK so far? Power up the motor and the generator generates your now isolated 115vac @ 60hz. Ok so far? Now mount a balanced 200lb flywheel on the shaft that connects the motor to the generator. So there you have it, isolated clean power. Make sure you house this monster in a cabinet that none of your kids can get into.
They didn't have the flywheel, but that was how they generated "clean" power on a couple research ships I worked. A motor driven by the ship's generators drove a generator that fed the "clean" (computer, instrument) power distribution. Kept the cycling of motors on hydraulic systems or slight out of "tune" running of the ship's gens or switching generators from glitching the electronics. Clean utility power is dependent upon your utility, where you are on the sub-station distribution, recent load additions, etc.
The amplifier and its power supply are closed loop systems with large overheads when properly designed. I don't see how anything further down the line makes much difference, although optical input or attention to the preamp environment will reduce conducted power line noise.
Paul you comments actually made a lot of sense, but a couple of questions How do you lower the impedance on the output relative to whats going in?, since Pin must equal power out?; is it the case you store large amounts of energy in order to do this for short amounts of time?, will the output from your inverter stage be out of phase with the incoming mains to further improve as per the points you mentioned?. Glad I watched this, changed my opinion.
Suzy Siviter I hope its ok if I reply. The mains regenerator has bulk capacitance (buffer) that stores enough energy to maintain a steady output voltage and frequency within the designed load capacity and input tolerance. The output waveform is re generated precisely and independently from the incoming supply.
Paul - where do you stand on the impact of the new audioquest Niagara series of power conditioners that is cleaning up existing power vs using a ps audio p15 or p20
At my old home there were power lines and equipment would get electrical damage constantly. The infrastructure looked dated and repairs were only made during catastrophic failures. After moving to a newer neighborhood with underground utilities I haven't had an issue. I use power conditioning on my main equipment now regardless. Some places have better power than others. If there's all kinds of noise in the lines, your asking for trouble.
I no longer worry about clean power supply to my system ever since capturing a Pikachu who does the excellent job as long as I feed him well and go out for a regular walk :D
The impedance of an audio power supply is largely defined by the storage capacitance. Large capacitor banks have high peak currents and large transformers have a better regulation factor and is less likely to sarurate. As the caps are charged with a 100Hz waveform, if the current drawn is inbetween the recharge timespan, the capacitors are directly affecting the sound. Having a choke input power supply works amazingly well it utilizes the full waveform. Powering sensitive gain stages from a regulated and fixed over audio band impedance supply, most of the issues of varying supply voltages and mains impedances can be overcome. In my point of view having an amplifer supplying another is a very costly, clumsy and inefficient means of improving a system. If we could raise the 50Hz to say 60Hz or maybe say 75Hz then yes then it makes sense to have a regenerator. This will allow more frequent but smaller sized charging pulses. Because the charging pulses are smaller, the noise generated by the rectifer diodes should also be less. The rippple on the capacitors will be smaller and that will definitely result in a more sturdy and clean supply.
Yes, exactly.. A properly engineered power supply is built for standard, regular AC without any need for external appliances (except protection from lightning, etc). This power plant is supposed to address voltage drop issues in a residence. But the proper way to address an AC voltage drop issue is proper wiring design. Between the receptacle and service panel verify that a conductor is installed that is properly size for the load. It's really that simple..
@Dave Micolichek no, I never said that. The proper size wiring is to reduce any type of voltage drop from the audio equipment. The other concerns are addressed by a properly designed power supply. These power conditioners are nothing but snake oil. The only benefit they truly have is the grouping of power receptacles, which helps to eliminate ground loops in unbalanced gear.
The transformers don't make the sound signal coming at the amplifiers output, the amplifier modules do that work... The power supply reservoir capacitors have the greatest role to play by smoothing out voltage variations and noise from the power supply... Voltage variations in the power supply are usually induced by the amplifier itself as it tries to draw highly complex currents from the power supply. (Music is not a simple sine tone but a VERY COMPLEX combination of them). This is the main reason I prefer having huge capacitance values in the power supply, usually by combining many smaller caps rather than 2 humongous cans. I believe what clean power does is eliminate EMI that usually finds it's way to the amplifier output (clicks, pops and buzzing and sometimes hissing noises).
masive difference can be heard using a serious headphone. What I miss in this video is turning around the plug which is also a huge difference. Maybe this is because in the US there is only one way to connect the plug in the wall outlet? In Europe you can put in the plug two ways. One way the plus is on the plus the other way around it is not which results in minor results. Now as I come to think of it if you use the power device current is converted into DC so probably then there is no difference anymore
Wouldn't not having "clean" power argument due to the reasons here also kind of collapse any argument saying that power cords make a difference? I am all for better interconnects but was always on the fence with expensive power cords.
as important as your marketing, that power regenerator probably adds more noise than it helps; there are a few theories? how about you measure it and show it to us
Another test I would like to see. As these Power Plants have a built in scope, I would like to compare the internal scope to an external analog scope monitoring both the incoming and re-generated AC line. So if the internal scope shows a crappy sine wave on raw AC, I want to see the same on the analog scope. Likewise if the output shows a perfect sinewave, I want to see that on the analog scope as well. You fellow EE's here can see where I am going with this.That internal display is a raster scanned LCD, not a true scope. Are those images accurate realtime samples of the AC or are they just static GIF or PNG images? And if truly sampled, what kind of weighting is being applied. Of course a lab grade digital scope is also acceptable, just needs to be a "real" scope and not some PC sound card solution.
My goodness you're a suspicious sort. The scope, as well as the THD analyzer, are real-time instruments. They are not scanned images. It's easy to see that and test that on a Power Plant. Yes, the scope's bandwidth limited to a couple of kHz but we're only interested in 60Hz and its close harmonics. Why would we give you anything but real instruments? That would make no sense. We use real A/D converters too! Amazing what good engineers can do, Andy.
It's called credibility. When you market AC power outlets claiming to "reduce midrange bloom" Power cords that have specific conductors for bass, midrange and treble? And you have yet to provide a technical explanation for those claims to spite my asking more than once. Hence my suspicion about the Power Plant. I want to see this "flat topping" And if I see it on the Power Plant scope, then by all means I will surely see it on a scope across the raw AC line!
The concept is hardly unfamiliar to me. What do you think amplifier clipping is? The question is how much 60hz sinewave clipping occurs in a typical residential power source and further how much energy, if any, is being lost. As usual in audiophile discussions you provide plenty of laymans theories but never any hard numbers to back it up. I would hope PS Audio owns at least one modern scope that can store and capture images. Show us some of the data you used when designing the PowerPlant. And of course once again you dodged the outlet and power cord question. You made the claims (you are the CEO), why can't you explain them in technical terms? How does an AC outlet reduce midrange bloom. Why would RF conductor technology applied to a 60hz power cord improve audio component treble response?
Oh goodness Andy. There's plenty of information available if you want to look. Your constant badgering and insults "I would hope PS Audio owns at least one modern scope that can store and capture images" are counter productive and tiring. We're a modern engineering company of 10 full time engineers with some of the best test equipment made. I haven't the time to invest in your education because your intent isn't to learn but to refute whatever I say. Life's too short for this. Here's what I suggest, if you're ever in Boulder you have an open invitation to visit our facilities where I will be happy to use real scopes and try and help you gain some insight. I do not have all the answers you currently seek, not in the form that would work for you. Some of my personal work is subjective in nature - something I realize drives you bonkers. Thanks for posting and viewing. You seem like a nice person and again, if you're in town, come on by. If for no other reason than to have a good laugh.
I think you dropped the ball on this one Paul. How do you justify using such a power supply on your Sprout100? Most important, is to have a well Earthed mains supply. Faulty equipment that does not go through Earth Leakage protection can cause havoc here, even if it is in your neighbors place. Most common by us would be a faulty water heater element. Then the Neutral to Earth voltage must be low. Here by us the legal requirement is less than 10VAC but I would recommend not more that 2V for good audio. Then you can start looking at noise on the Live conductor but generally if the Earth and Neutral are good, most decent systems can filter out the noise on the Live. Balance line (XLR) input / outputs are much better at eliminating noise than unbalanced (RCA) Fortunately I can check all this for myself but good luck finding an electrician who would care two bits.
whats Earth Leakage protection? My gear is on the ground on my dedicated 30 amp romex line to a 30 amp fuse whatchacallit in my house breaker box. I didnt hear any improvement but I havent A-B'd it though with a non dedicated line like a shared house outlet. For a long time i had the ground run out to an iron rod buried in the ground. Again no improvement really -- in fact a lightning surge came and destroyed alot of my stereo and nothing else in the house, and I dont understand why, but maybe the surge was attracted to the dedicated ground to the buried rod , as THE 'path of least resistance' for the surge to follow?
@@rd264 Hi. Earth Leakage Protection Units (ELU or ELCB in othercountries) are a requirement in my country to protect people against electrocution. This is required because we run at 240V as opposed to 110V in your country. An ELU is made to sniff out low Leakage currents (20mA or so) and isolated that part of the circuit if such a Leakage is detected. Unfortunately an electronic system has to work together as a whole to be effective and safe. In your case, you effectively had your sound system between the external earth and the electrical system in your home. This is totally counter productive and unfortunately this matter is way to complex to clarify here. My recommendation is to befriend someone in the field or to do a lot of Googling.
Paul, I want to thank you for the information on "clean power." You were talking about how these AC Conditioning devices effect the higher frequencies. I've always had my amp (Parasound A51) connected to my $3000 AC conditioner (not from PS Audio), assuming the sound was better, and never questioned it again. But watching your video, I thought, "I'm going to plug the amp directly into the wall without the AC Conditioning." I'm here to say, "it sounds better!" Much better. Ugh ($3000?). The higher frequencies are where i notice the most difference, more pronounced, more extended, and everything seems more airy and refined. I was surprised. What have I been doing all this time?
Hi Paul. Since I am retired and on a fixed income (and have a modest, but adequate system), I can't afford expensive power conditioners. However, I noticed a big improvement after I added one of your "Noise Harvesters".
All i needed was a oversurge protector it worked fine, but when i bought a ups wow it was like night and day, so try it out yourself, it æ does not need to be an expensive investment at all btw.. try it out yourself and find out whats best for your house
yup eddie van halen used a variac to get his sound from his guitar amps. voltage systems are used all the time for guitar amps at shows. so do recording studios
I strongly agree with Paul, power plants are awesome! I invented a device that is used at the input and output of any Power conditioner, patent pending... This one is a game changer, no snake oil... "Device adds energy / synergy characteristics to electronic audio and video devices, which result in a richer sound, with less noise and improved dynamics & timbre. In regards to video, there is an improvement with contrast levels and richer color enhancements, and overall cleaner images." Stay tuned fellow audiophiles... Currently searching for a company to license from me, once this hits the shelves, it will cause controversy among the audiophile community. All cable manufactures will hate me, we're talking about a solid 10-20% quality improvement, not psychoacoustics...
I guess most people doubt this because they dont notice it and it really depends on how clean the power is that your using. I think a power supply on DAC makes sense - also optical digital audio (toslink) seems better than USB. Do I notice it? - I dont think so! Will I buy a good power strip with build in surge protection and power conditioner? -Yes! I think so. Its fundamental!?
Clean Power is not that important as long the Power Supply inside your equipment have a good design and a good filtering and ripple clean up. You have to notice that digital equipment also creates noise by itself The individual transistors inside the chips create noise every time then turn on and off. The end product your amplifier needs is DC and as long your DC is constant and voltage is maintain steady and ripple free I think you are home. The end game in an amplifier circuit is the DC from it's own PS.
Hi Paul, I appreciate your wise advices and I find your way to tell very affordable to all of us. After this brief introduction I want to say something. What I'm going to write along these lines don't pretend to be taken seriously because even I or me, sorry for my grammar althought it's not the subject of the matter here, well, the truth is that after 30 years of being actively, read:expending money, I'm not sure of anything related to the truth of the hi-end as I imagined when I was a novice full of illusion but empty of currency. During those years, I could detect if I had cleaned the contacts or not, if my toslink fiver optic had been cleaned with alcohol or gel to wash dishes, I compulsively changed the polarity of the power plug and noticed differences but, Which one was better? It depended, even from my mood... I could go on and on and I'm so sure this same thing happens to a lot of audiophiliacs, sorry Steve Guttenberg for borrow...ing? Your catchy adjective ha ja ha, when one begin to behave like this, better check it out with a pro or stay away from some time of your beloved equipment, after a while, you will again start to enjoy the sound of your rig and the minute differences once were amazing, now are meaningless. The real character of the sound system won't change by some 'trivial' actions one could try so if the sound in not to your likes, give it to a friend, he will be eternally grateful without ever suspicing you gave the leftovers 😂...etc...etc.
If your rectifier diodes are only switching at the peaks of the sine-wave, then that means your bulk charge capacitors and transformer are doing their job well. In other words, your amplifier's power supply is keeping up with demand. No worries. If your DC rails are sagging, then your probably playing your stereo very loud. At lower volumes the AC supply impedance wouldn't be critical at all. So if your to the point where you are having AC supply problems, it seem to me it would be far more effective to run a larger dedicated AC circuit to the power amp/s from the circuit breaker panel. Maybe go one cable size larger too. Try #10awg copper. But a re-generator??? Really... how do you sleep at night?
Chris H Exactly.. If the voltage sags at its input, then there may well be a voltage drop in the circuit conductors. A larger conductor will solve the problem..
And to that point, at moderate volumes, voltage sag wouldn't be a problem and even when it does occur, the high CMRR of the amplifier insures that you won't hear it unless your dumb enough to let your amplifier clip. That's one of the things the feed back circuit addresses.
Paul P. I rather doubt a "HUGE" difference. Maybe some difference and most of that placebo. And a "difference" doesn't automatically mean an improvement. If I would have heard or seen an improvement I would have kept the conditioner in the system. My system as is, is about as clean as it gets when listening to music. Much more to be said of a quality XO in a speaker system than connecting to some line conditioner.
Paul P the differences are always small, a little more depth, a little wider, better seperation, tighter bass, etc, but not huge. And in Milton's case no difference at all. It all depends on perception and the rest of the equipment. I dont notice the difference on my home stereo, medium to high end system, but on my stage piano I do notice the difference very easily, but that came with a small wall adapter, but I was glad that I could notice it, since the wall supply is $4.- and the power transformer, filtered, stabilized costed $400.-
It's obvious that clean power will make a difference, just not a big one, everyone in the comments needs to chill out and stop screaming about snake oil, this is real science but it's not gonna make a blind bit of difference to your 1990's boombox is it?
I wonder if studying circuitry of neve preamps has any overlap.. well, they’re not tube but do tube amps for home audio have input/ output transformers?
I recently put two AC filters in series, daysy chained, and believed or not, the improvement was staggering, really hi-end, and all for less than 100 euros. I'm not saying that one can do this and expect a miracle but if all the parameters are being improved, acoustics, stands and rack included, we can reach places never dreamed possible within a constrained budget. After tuning one's equipment, then, can we forget about formats, sources and meaningless disquisitions and be carried away by the music.
If the power supply in an electronic product designed to operate from a domestic mains supply needs another piece of kit to function properly in the presence of some noise, the power supply is not fit for purpose. Normal levels of noise a user could reasonably expect to see on the mains should be rejected by the PSU's input filters without difficulty. There is a valid argument for protecting equipment against transient surges and brown-outs and how much somebody wants to spend to achieve that is up to them.
I agree. Besides which all modern appliances which can create interference are fitted with filters anyway. This is entirely routine in both The US and The EU.
The power signal is probably the most important aspect of audio reproduction. Whatever source you are using, it is the incoming power signal that acts as the carrier signal in the modulation process. Just like AM radio (Amplitude Modulation), there is a carrier signal whose amplitude is controlled to represent another factor, in the case of AM Radio, the amplitude of a particular radio wave is modulated to represent frequency. In standard audio reproduction, it is the incoming power signal that gets modulated by varying its voltage to produce the final output signal. This means that however clean your incoming power signal is, your recording can only ever be as clean as the incoming power, because it is the incoming power that gets modulated to produce your final result. The power signal is your carrier signal in the modulation process. The better quality the carrier signal, the better the result.
So, the 60HZ AC power signal coming through your wall, you say it's not a "signal"? What is it, then? You're being pedantic. It is a signal. But even disregarding that sticking point (which you are wrong about), it still acts as the carrier signal in the modulation process. Perhaps you should read about modulation a little before being a pedant.
Well, I guess that by using a 40kW on-line UPS for my house I probably get a rather low line impedance. Probably not as good as using such an UPS or a power regenerator just for the audio stuff, but better than what's coming from the city.
Indeed.. He's selling a product to correct potential voltage drop on an AC circuit.. The proper remedy is to simply increase the conductors of the circuit. Problem solved, no snake oil needed..
in car audio there is a belief that the cleaner the power going in (as in as little voltage drop as possible...) the cleaner the power going out. to a degree it kind of depends on the audio that youre running. lol home audio may not be as bothered by "dirty" power as much as some others. but i do know that dirty power can in some cases cause audio failures. 🙄 having an amp fail is never fun. ive had a couple fail. one was because of very crap power source.
Too funny.. A diode doesn't truly "switch".. It conducts.. Also, voltage has nothing to do with how often that the rectifier bridge conducts.. That is based on frequency.. Paul doesn't understand basic electronics.. Complete nonsense..
"Too funny.. A diode doesn't truly "switch"." Analysis and Characterization of P-N Junction Diode Switching, a. J. KUNO, MEMBER, IEEE in IEEE Transaction on Electron Devices phylab.fudan.edu.cn/lib/exe/fetch.php?media=exp:minor_carrier_lifetime:analysis_and_characterization_of_p-n_junction.pdf
I've a feeling there's someone here who doesn't fully understand electronics. So that's basically true. I don't think that person is Paul though. Sometimes a little bit of knowledge can be a dangerous thing.
Well, a diode doesn't switch in the same sense as a mechanical switch. However, when used as a simple rectifier it is correct to use that term. Again, once you got a clean DC voltage after filtering and regulation all is good. An amplifier or any other equipment doesn't have a mind of its own and doesn't work differently depending how the DC voltage is generated. If anyone is so concerned the best way to power your HiFi would be a big bank of deep cycle batteries backed with a big bank of huge low ESR capacitors and bypassing the power supply in each system.
I can assure you that I understand electronics quite well.. Again, I stand by what I said.. A "true" switch typical opens a circuit while a voltage is still applied to it.. This is the case for a mechanical switch, a relay, and often a transistor.. But this isn't really true for a diode.. It doesn't open the circuit while a voltage is applied.. Instead, it conducts (or doesn't) based on rising or dropping voltage. It is simply reacting to its voltage source.. Similiar terms, but there is a distinction.. And I agree about the rectification.. The rectification process itself is in essence a "filter." And anyway, most noise issues can be traced back to ground loops--hum at 60 Hz and buzz at harmonics.. None of the gimmics will solve this problem.. They are solved by good installation practices...
Clean power only matters to low voltage. Adequate capacitors and regulators on the primary and secondary on a power supply as well as metal covers to filter noise is good enough. Also, using LEDs with decoupling is very important as well. Diodes by themselves are very noisy, just drive by a traffic light with LEDs and listen to an am radio station. The buzz is obvious
are you saying that it does not matter at all for amplifiers and cd players and if so why? My integrated Naim XS2 for example is 70 watts/ch, it draws about 16 VA - 350VA [~ 16-140 watts]. My cd player draws 30 VA.
An the reduction in noise level when everything in quiet permits or allows the listener to hear a greater dynamic range at the same spl, I've been thinking about this recently and I think that that cause of less noisy environment could be the reason of an improved audition. What would the results be in a rainy night ? I'd bet my farm, if I had one, that the sound wouldn't be so pure without being the electricity the cause, after all, everybody is in bed don't agree?
Salvador Rodenas it’s also less noise in power line not to mention psychoacoustics and biorithms. Concerts mostly held at nights in darkened rooms after warm up act for a reason.
clean power can is important as noise could cause malfunctions like for example could interfere with the stereo detection circuitry for the fm tuner causing the indicator to come on falsely (this is a problem on tv when they are broadcasting a sports event the crowd noise can falsely trigger the sap channel partially muting the rest of the signal. it can also cause for example the stereo to turn off if the power button is one of them soft switches that triggers a transistorized latching system. there is one place you can hear the difference as today's digital electric utility meters phoning home to report the power usage there is a interference that shows up as a square wave buzzing noise you can see the interference as flickering of the cheap led lights that are simply a resistor capacitor dropper and a diode to convert to dc and no filtering capacitor.
Let's first create a problem so that we can then be seen to be creating a solution to the initial problem that need not be a problem at all then everyone will think we're so clever and believe everything we tell them.
For Brad Smith and rest of the FUD salesteam, PS Audio offers a free 30 day in-home trial, including 2-way shipping, so if any PS Audio product doesn't work for you, simply return it. And Brad? I'd like to return your advice: It's not worth what I paid for it.
Gruss Gott Are you talking about this specific Powerplant product, which sells for thousands?? Of course, I can't tell you what to do.. But I will say that there is absolutely NO way I would purchase this product.. Good luck!
Sure, but then your decision is made from ignorance given you have no actual experience with the product - experience that's free for anyone to acquire.
You can buy a perfectly decent UPS with true sine wave filtered outputs for around 1000 bucks or less and backed up for a decent amount of time too, not just 30 seconds.
I appreciate this guys honesty and educating his audience on what they're actually buying
I was abused 2 days ago for making the same statement, obviously trolls or people who think their opinion is just right.
I'm still trying to figure out how the cord in the thumbnail with 3 prongs is going to fit into that wall socket
I think Paul does a fairly decent job of explaining here. At least he states that it is not as important as many think, but can be important depending on situation. Also, one doesn't need to spend $10k on a PS Audio power unit or any power unit in that range. On the flip side I have never seen power units at Walmart and would not purchase anything from there anyway. I never needed anything like a power conditioner until I moved into this one place that had sketchy power. I went and got a Panamax power conditioner/protector (expensive to me, but not nearly as much as a PS Audio power unit), but it solved a list of problems and saved my gear a couple of times and it is still doing it's job. If one doesn't have measurable sketchy power in their place, then it is not likely things like power conditioners are needed. Always a good idea to have a good surge protector though.
As always with PS Audio stuff it would lovely to have; But Paul's point that it is the verry crests of the voltage peaks being 'Cropped' as your most likely disadvantage caused by using a power conditioner I frankly doubt will be a problem with a{£30] 1000w conditioner with surge protection etc running little more than a hifi system.
I once had a situation where l had a power surge that took out a VCR. The power company did a chart on my line for 3 days and found spikes. They discovered over the years that 5 houses were on the same transformer, this by itself back in the early day wasn't to bad but home owners added to their homes. New AC pools new kitchens etc. But didn't tell the power co.
This caused overloading.
Finally l recieved the power surge and spike.
The remedy
Give me my own 25kva transformer.
Suddenly Clean voltage amperage and more!
No more problems and great audio/video! Yippie!
Thanks for the explanation on lowering the impedance, as it impacts the sound. Also the rolling off of the sine wave. These two items explain why I got better sound when I replaced my cheap .75 wall socket for an Audiophile Grade (better than Hospital Grade) wall socket. And when I included a linear filter on the power line. That linear filter actively keeps the impedance low at .05 Ohms. The socket, creates far better conductivity to the live power wires in the house. As it turns out, those cheap Home-Depot special power outlets have no copper behind them and the plugs themselves are loose and do not make cold welds against the power plug. Hospital Grade does have some copper behind it, for better and more reliable conductivity and has tighter plugs to make a cold weld against your Positive/Negative/Ground connector.
I bleach my power cable. Nice and clean.
😂
Ive never tried that
This is the way.
@@edwardmarcus7288 This is the way.
Lol.
7:41 Kind of rhetorical question, does it matters if the AC power going into the power regulator comes from the golden 'audio grade' power cable that costs $600 or regular power cable that costs $10?
That's what your amps transformer does, it lowers the impedance to a specific setting in Ohms of power coming into the amp. You don't need a high-end clean power component in most major cities when one has a good transformer built into your amp. Every high- end audio company will list the transformers filtered amp impedance in terms of THD (Total Harmonic Distortion). What one really needs is a high quality surge protector. Save your money and invest in four of the most important products of any high- end system. 1) A great recorded musical source 2) A well built amp with a large high quality transformer. 3) A high-quality surge protector. 4) High quality efficient speakers that match the Ohm setting of amp. Then add roughly 20% of total cost of system on cables. Look into companies like Acoustic Zen, and AudioQuest for cables, just my opinion.
Absolutely. It’s nuts. Bunch of scammer baby boomers everywhere in audio apparently.
This is good information as to why. never heard it explained this way before. Great job!
some psychoacoustic + placebo effect + woo woo is the highend audio world. Sad but true.
There's really simple phenomenons regarding power supply: noise (which is typically rejected by the transformer itself or the input common mode filter or PFC of SMPS), having enough power reserve in the bulk capacitors for transient power requirements of the amplifier and bus pumping. If an amplifier runs out of power, distortion is pretty bad, so there's no magic here.
These units are basically a double conversion topology UPS unit missing the battery backup. Yes they do re-generate clean low distortion AC to spite noisy or distorted input AC power.
The question is if typical residential AC power is so bad that these units can make improvements in the reproduced audio. In most cases I don't think so. While some areas of the country do have bad power, the average home is more than good enough for fine audio reproduction. 3% to even 10% distortion on the incoming AC waveform will not compromise any competently designed linear or switch mode power supply, especially a switch mode power supply. The AC is rectified, what difference does some distortion make provided it does not change the RMS value significantly? Distortion on the input AC does not translate to amplifier output distortion. Now that is not being claimed directly but I think it's being assumed by non-technical customers.
Another thing to keep in mind here, the Power Plant is still plugged into the so called dirty AC power. While I do believe it does produce a low impedance output, let's ask for how long? The PS Power plant can maintain this low output impedance only as long as it's internal power supply reserves hold up. Now does it hold up long enough to ride through average music transients? We don't know but that can certainly be tested.
I would be interesting to run some tests comparing the amplifier DC rails against an audio clip on a quad trace storage scope with and without the PS Power Plant. I expect there will be some difference but then we have to quantify that to the performance of the amplifier circuit.
How would these PS-afficionados respond once they realize that the output stage of the Powerplant is actually eerily similar to a, ever loathed, Class D amp... ;-)
I understand it's easy to dismiss this because it doesn't quite fit your view but you might try giving these newer ideas and concepts a try. I've done my best in the short period of time I have to explain AC flat topping and the importance of refilling the missing energy as well as regulation. One thing to try and remember is that most power amplifiers have unregulated supplies and these are impacted even more by producing a distortion free sine wave. The only reason we measure (and provide an analyzer on the front panel) is to show the effects of clipping the AC waveform which, as I am sure you understand, happens when enough low power factor products on a shared line draw current at the peak of the sine wave. Lastly, this is only like a UPS in a distant way. A double conversion UPS, while functionally the same, is not the same. That's because UPS regenerators are class D amplifiers and they cannot deliver high amounts of peak current. This means that when they try and power low power factor devices they can actually make the power worse, often as high as 10% to 15% in the form of a divot in the sine wave at its peak.
PS Audio UPS's indeed regenerate their power from batteries that are (arguebly) slower to respond to fast changes. However, Class D amps, or frequency inverters which are in essence very similar, generate their power from high storage capacitors, that are very fast to respond and can handle transients perfectly fine.
So I don't quite get your point.
Class D amplifier, in the way they are implemented in double conversion regenerators cannot deliver peak current. They do fine when the power factor is 1 (where voltage and current track each other) but when it begins to dip below 0.7 they cannot keep up. If you're really curious you can easily test it. We use a 500 watt variable power factor load and test all sort of devices. Nearly all fail. The problem is these peak currents can often time exceed 60 amps right at the peak of the sine wave. When we design and build a regenerator it has to handle these peaks. To do that requires enormous banks for power supply capacitors and very tough transistors. That's a lot of peak current.
PS Audio There's something seriously wrong with the design, when an household appliance's power factor dips below 0.7
Anyway, in the mills where I work as an electrical engineer, we power motors of several 100's of kilowatts in a similar way, to how a Class D amps functions. These motors do not cringe and when in normal operating mode, they usually don't fall below a power factor of 0.85.
It's all a matter of size. When the converter can't keep up... it's too small... Replace it with a bigger one.
I have a tube guitar amp, the question is if i am better with just a extension of 230V with surge protection on my 16A eletricity socket on the wall or a APC UPS with 1400VA and 700w 230V with a pseudo sinewave? Or both? The tube amp only have 25w, and consumes 100/115w in full power. I will connect a Line6 HX Stomp and a CryBaby wah pedals in the FX Loop circuit in the amp. I live on Europe, Portugal to be precise. My house have 30+ years, should i check my circuit breaker for better ground? I have a circuit breaker that the only thing it controls is the suply of energy to that 16A eletricity socket. In the future i will buy a Furman but meanwhile i just want to know what is the best choise in my case. Thanks in advance. I know 0 about eletricity. I will loose dynamics with the UPS? More than with just the extension?
I am getting random popping coming from my def tech 6080 towers even with everything turned off but the towers plugged in the wall. could the built-in amps have issues? bought in 2009.
Interesting bit on impedance. I run a tube amp connected to a separate tube preamp and tube dac...and I'm quite happy with all my distortion.
Nice! Yup saturation is why old recordings sound cool. But then again there’s a lot of those; tubes optional, to hear it
I'm late on this tutorial. Great topic and my brother (In the 70's Nippon engineer) was passionate about this. He built for me, a solution for the trash that the 'power' companies sell us ( eh showed me the proof). He said Audio/amps/refrigerators etc., are engineered for a correct fuel/power. You are correct on this, I've noticed most audio businesses do not push these benefits. Today my entire home has this benefit. (My 74 Sansui is still pushing it. NO repairs) Thanks brother...
Amen brother .. I constantly tell people that the only way to get true. full , dynamic sound from your refrigerator is to get rid of the trash that the 'power' companies sell us and use a 60hz-60hz rotary phase converter. When you run a fridge off straight wall power you loose all the bass.
Hi,
We use a cheap generator to power our music gear. Guitar amps, P.A etc.
Could the power it produces be damaging our equipment?
Do we need to put a power conditioner or surge protector or something between the generator and our gear?
Clean power is important for the business of PS Audio.
You really should think better. Don't deserve that name.
Paul P. Well, my point is correct. If you assume that my indirect point is that clean power often isn’t a relevant issue for most consumers and sold as snake oil a bit too much, you are right. Modern consumer electronics has build-in mains filters and power supplies intended to keep mains noise away from amp circuits. If your amp doesn’t have Vcc ripple or other noise measurable originating from the mains noise, you are fine. Electric noise is 100% measurable.
ABSOLUTELY!
ThinkingBetter to Paul or PS Audio, it's magic
actually if there was not a problem
Perhaps capacitors provide a buffer to absorb peaks in demand from the Amp?
Very informative. With a transformer-rectifier-capacitor supply the impedance of the mains really comes into play when the diodes conduct on the peaks to keep the capacitors charged. So you listen to a combination of mains (inc transformer) and capacitor impedance and rectification quality. I have used transformer-rectifier-choke-capacitor supplies to good effect to eliminate the short conduction spikes. I guess without using synchronous rectification which will inevitably demand a move to switch mode supplies, this interaction with the mains will always remain. Switchmode technology has made big advances and one could always use decent amount of capacitors after the SMPS. It is already used succesfully in your power regenerator.
What’s the best option for clean power spending less then 1000 dollars. I use isolation Transformer system for cleaning the power to my Hifi system and it makes everything sound better than whiteout it I have two one small 100w isolation transformer that I use for Preamp and cd player and one big isolation transformer 1000w that I only use for small power amp Rotel 960BX 300w in effect and the power amplifier also sound better than whiteout it. I have also tried Isotek the plug shunt filter but my Hifi system sounds much better whit the isolation transformers. Totally isolating and regeneration of the power can be done whit a UPS 3000w system using caps and battery to store power but the UPS uninterrupted power system have to be built for Audio use. One other option is battery power and True sine wave 3000w inverter. It,s going to totally isolate power from the grid but the quality of the power output is going to be down to how good the inverter is to recreate 12v DC power to 230V 50-HZ sine wave power.
Hi Paul
It would be nice if you talked about Transmissionlines.
Not many know them and even less how they work.
what about if i want to play directly from dc power (huge pack of batteries) on my hi end system ?
battery power seems like a good idea if only for phono stages and preamps --- its alot less expensive than what PS Audio offers.
*I have a couple of Mr Tice's power blocks, makes a big difference - previous home I had added an isolation transformer on a sub-panel with 12ga wiring to the outlets all together made a HUGE difference*
Snake oil. Spend the extra money on a better pair of speakers or power amp or both. No power conditioner/regenerator can help a power amp with lousy power supply circuits inside the amp. If it is your house, pull a heavy cable from the breaker box to just power the system, that will do a lot more good and a whole lot cheaper.
I have owned a P10 since 2016 - very happy with it - powers a pair of 300 watt tube monoblocks., Listened to it with the Australian distributor, who describes music played through it as "sounding more organic" compared to a voltage correction device (Thor PS-10) which didn't condition the power amplifiers.
May be a dumb question: why not use a battery based generator like ecoflow? I am not listening to music all day, at least not at that level. So I am ok with the batteries only lasting a few hours. How good needs the inverter in such a solution to be to get „clean“ power? i still have the influence between the different music components. Is earthing a problem?
I'm no expert on the subject but this really makes little sense to me. I highly doubt that in a blind test one would ear the difference when using regular power and "clean power". I bet that the placebo effect and the sense of ownership of very expensive gear will make one think that the sound is better. If by any means a piece of equipment "messes" with the signal I would say it would be for the worse and not for the better.
Power conditioners absolutely make a sonic difference. The difference will not necessarily slap you in the face. But while listening with clean power, you will unexpectedly find yourself in "the zone".
The real reality check will be after you have been listening with clean power for a while. Then, remove your power conditioner, and your music will lose its magic. It will sound more two dimensional and congested.
Please note that:
1) no power conditioner, at any price, will make a difference on a $99 stereo purchased from Walmart. You need to have a good stereo, proper speaker placement, etc, in order to reap the benefits of clean power.
2) not all power conditioners help. Some will make your music sound worse.
I have listened to products from Shunyata Research and Audioquest. Both make a beautiful improvement, with no downside. I would give Audioquest the edge.
PS Audio's power products might also be very good. I never auditioned them.
Cheers!
I dont know, I was sceptical, but after listening to Paul; the points do at least make sense from an electronic engineering perspective; but only on equipment that uses switch mode power supplies, it wont really improve a standard linear supply; because linears have large capacitor values with lots of stored energy anyway.
car ....it's engine ...normal fuel.....change that fuel the a higher octane fuel......think ...your amp will get more power per watt .....
Any expensive equipment you buy makes you hear the difference, trust me!... You can clearly hear your SO yelling at you for wasting money on pointless crap!
Because you haven't watched the whole video. Start from 7:00 key at 7:30
I heard someone say you can get bad power if you use a surge suppressor strip. And suggested to plug it directly into the wall. But here in Florida would be disaster with all the storms.
Does anyone know how to stop the clicks coming through my guitar signal?
Paul, we need more videos about your products. Love your videos, thanks !
I am hearing from some audiophiles that by using power conditioners, you are loosing dynamics from your system. Which is why I ditched mine for the wall plug.
A power conditioner on the AC side should have NO EFFECT on the dynamics of your audio signal. The ONLY reason a power conditioner might be desired is if your local power is subject to frequent brownouts or dips.
Otherwise the amplifier itself should have a well designed power supply and have no requirement for a conditioner at all.
Don't listen to audiophiles either way.
Probably needs it if you live in third world countries. But then again you won't be able to afford these, if you live in third worlds.
I always doubted this until I heard a DAC sound better with external power supply. Suddenly, as a novice audiophile, I can see why clean power makes a difference.
Sounds like the difference between a bad and good power supply. A common issue. Saving a few euros on a proper internal supply.
Seeing as every amplifier on the market runs on DC internally and has a fairly decent filtering circuit after rectification (filter caps, coil chokes/inductors, hell even internodal resistors), I posit that the design of the power supply is the important factor here - NOT the AC mains itself. As long as the AC is reasonably low noise, which it almost always is unless you have something else on that circuit misbehaving (cheap crappy computer power supplies, for example, often can throw tons of noise back into the mains lines), it doesn't matter. As far as voltage sag - that's not a problem, unless you have a wildly under-spec power supply, or for some inexplicable reason you're using vacuum tube rectifiers.
I would say that the average American home that had a pretty good stereo system would also have things plugged-in on various circuits that create noise in both the power and electromagnetic realms.
what about all the noise behind the outlet and all back to the electrical box and outside power lines?
I am a recording engineer with a very keen ear for frequencies, I can hear difference when mixing between .1 db and 0.2 db, to me it's possible to hear that, so I am not going to say I am like the rest of people.
BUT I am not chasing perfection of sound signal, but recently I have encountered something that I cannot forego, I started having constant clipping sound in my speakers. I thought it was the amount of buffer from my recording equipment, even when listening to RUclips or playing games. Then I started getting clicks and pops when AC unit came on much more severely, and I realized that clean power is an issue for me. I recently bought Voltage Regulator from Furman and will do further testing. I understand some chase some glorious "Holy Grail" of sound like Detective Monk, and usually never find it. Me on the other hand, I try to have an easy listening experience without clicks, pops, or buzzing in my speakers, that gets really painful when you are tired or pissed off about life, and you got this gnat in your ear going BZZZZ *CLICK-CLICK-CLICK-CLICK-CLICK*
Some don't even hear it, so why would it bother them?
I throw my electricity in the laundry wash every day. Shockingly clean as a whistle every time.
Over the years, I experimented with an array of power conditioners, filters, ups/battery backups, surge protectors, isolation transformers, etc. One problem that none of the power conditioning units I tried could fix was mechanical noise from the power transformers in all of my audio gear. These noises came and went. (My wife had a hairdryer that was a huge cause of this problem.) I finally tried a PS Audio Humbuster. Poof! The noises were gone, never to return.
I bought a $60.00 power conditioner to use with the PS. Sprout and B&W 602's. And WOW!!!! I love my Sprout even more. I can't afford the expensive gear gut I hear the difference already. It's not my imagination , it's real.
This is such a difficult thing to convey, a never-ending topic. Like the quality of the rest of the connections.
I disagree. After hearing the Isotek Aquarius in Oslo HiFi Center on some KEF floor standing speakers and a Rotel integrated amplifier i could really hear a significant difference. Especially in the bass area. I switched back and forth between ordinary cables and Isotek's own power cables and the Aquarius. The result was the same every time. Better sound without losning any dynamics. My brother was there also and he just nodded his head and said the same.
Sir, what if we use switch mode power supply to an amplifier?
I've seen lot of home audio system manufacturers like sony, jbl and Harman kardon systems use much better smps units nowadays
Fun story on this subject. One computer installation I saw in an industrial location that was experiencing extremely bad mains power. So they used a crazy device that is both simple and muscular. So, three parts of it. First a motor, and a big one. Lets say something like a motor that runs a pump for a swimming pool. Second a generator. You turn the shaft on the generator at 60rpm and it generates 115vac. It’s gonna be big generator. Connect the motor to the generator with a shaft. OK so far? Power up the motor and the generator generates your now isolated 115vac @ 60hz. Ok so far? Now mount a balanced 200lb flywheel on the shaft that connects the motor to the generator. So there you have it, isolated clean power. Make sure you house this monster in a cabinet that none of your kids can get into.
Can't deny the simplicity of that. Little concerned about the efficiency, though.
They didn't have the flywheel, but that was how they generated "clean" power on a couple research ships I worked. A motor driven by the ship's generators drove a generator that fed the "clean" (computer, instrument) power distribution. Kept the cycling of motors on hydraulic systems or slight out of "tune" running of the ship's gens or switching generators from glitching the electronics.
Clean utility power is dependent upon your utility, where you are on the sub-station distribution, recent load additions, etc.
The amplifier and its power supply are closed loop systems with large overheads when properly designed.
I don't see how anything further down the line makes much difference, although optical input or attention to the preamp environment will reduce conducted power line noise.
Paul you comments actually made a lot of sense, but a couple of questions How do you lower the impedance on the output relative to whats going in?, since Pin must equal power out?; is it the case you store large amounts of energy in order to do this for short amounts of time?, will the output from your inverter stage be out of phase with the incoming mains to further improve as per the points you mentioned?.
Glad I watched this, changed my opinion.
Suzy Siviter I hope its ok if I reply. The mains regenerator has bulk capacitance (buffer) that stores enough energy to maintain a steady output voltage and frequency within the designed load capacity and input tolerance. The output waveform is re generated precisely and independently from the incoming supply.
Paul - where do you stand on the impact of the new audioquest Niagara series of power conditioners that is cleaning up existing power vs using a ps audio p15 or p20
At my old home there were power lines and equipment would get electrical damage constantly. The infrastructure looked dated and repairs were only made during catastrophic failures. After moving to a newer neighborhood with underground utilities I haven't had an issue. I use power conditioning on my main equipment now regardless.
Some places have better power than others. If there's all kinds of noise in the lines, your asking for trouble.
Wouldn't the ideal situation be that all components do the cleaning voodoo before feeding power to the audio circuits in the machine,?
I no longer worry about clean power supply to my system ever since capturing a Pikachu who does the excellent job as long as I feed him well and go out for a regular walk :D
😂
Woah! What a great vid thanks Paul!
The impedance of an audio power supply is largely defined by the storage capacitance. Large capacitor banks have high peak currents and large transformers have a better regulation factor and is less likely to sarurate.
As the caps are charged with a 100Hz waveform, if the current drawn is inbetween the recharge timespan, the capacitors are directly affecting the sound. Having a choke input power supply works amazingly well it utilizes the full waveform.
Powering sensitive gain stages from a regulated and fixed over audio band impedance supply, most of the issues of varying supply voltages and mains impedances can be overcome.
In my point of view having an amplifer supplying another is a very costly, clumsy and inefficient means of improving a system.
If we could raise the 50Hz to say 60Hz or maybe say 75Hz then yes then it makes sense to have a regenerator. This will allow more frequent but smaller sized charging pulses.
Because the charging pulses are smaller, the noise generated by the rectifer diodes should also be less. The rippple on the capacitors will be smaller and that will definitely result in a more sturdy and clean supply.
ie you rec against the ISOTEK Genesis and the like?
Any resident noise on the line, is properly filtered out at the power supply of your components .
Unless the power supply is complete garbage which is usually not the case anyway.
Christian Holmstedt Exactly
Yes, exactly.. A properly engineered power supply is built for standard, regular AC without any need for external appliances (except protection from lightning, etc). This power plant is supposed to address voltage drop issues in a residence. But the proper way to address an AC voltage drop issue is proper wiring design. Between the receptacle and service panel verify that a conductor is installed that is properly size for the load. It's really that simple..
@@christianholmstedt8770 certainly not in expensive PS audio gear would one assume! :)
@Dave Micolichek no, I never said that. The proper size wiring is to reduce any type of voltage drop from the audio equipment. The other concerns are addressed by a properly designed power supply. These power conditioners are nothing but snake oil. The only benefit they truly have is the grouping of power receptacles, which helps to eliminate ground loops in unbalanced gear.
How do you properly size one for your system?
Thank you Paul. U saved me about 10k. 👍💪👊
The transformers don't make the sound signal coming at the amplifiers output, the amplifier modules do that work... The power supply reservoir capacitors have the greatest role to play by smoothing out voltage variations and noise from the power supply... Voltage variations in the power supply are usually induced by the amplifier itself as it tries to draw highly complex currents from the power supply. (Music is not a simple sine tone but a VERY COMPLEX combination of them). This is the main reason I prefer having huge capacitance values in the power supply, usually by combining many smaller caps rather than 2 humongous cans.
I believe what clean power does is eliminate EMI that usually finds it's way to the amplifier output (clicks, pops and buzzing and sometimes hissing noises).
masive difference can be heard using a serious headphone. What I miss in this video is turning around the plug which is also a huge difference. Maybe this is because in the US there is only one way to connect the plug in the wall outlet? In Europe you can put in the plug two ways. One way the plus is on the plus the other way around it is not which results in minor results. Now as I come to think of it if you use the power device current is converted into DC so probably then there is no difference anymore
Wouldn't not having "clean" power argument due to the reasons here also kind of collapse any argument saying that power cords make a difference? I am all for better interconnects but was always on the fence with expensive power cords.
Well obviously you should pick regulated power over clean power.
as important as your marketing, that power regenerator probably adds more noise than it helps; there are a few theories? how about you measure it and show it to us
Your comment is a contradiction to your user name. Stop overthinking and get some experience.
Another test I would like to see. As these Power Plants have a built in scope, I would like to compare the internal scope to an external analog scope monitoring both the incoming and re-generated AC line. So if the internal scope shows a crappy sine wave on raw AC, I want to see the same on the analog scope. Likewise if the output shows a perfect sinewave, I want to see that on the analog scope as well. You fellow EE's here can see where I am going with this.That internal display is a raster scanned LCD, not a true scope. Are those images accurate realtime samples of the AC or are they just static GIF or PNG images? And if truly sampled, what kind of weighting is being applied. Of course a lab grade digital scope is also acceptable, just needs to be a "real" scope and not some PC sound card solution.
My goodness you're a suspicious sort. The scope, as well as the THD analyzer, are real-time instruments. They are not scanned images. It's easy to see that and test that on a Power Plant. Yes, the scope's bandwidth limited to a couple of kHz but we're only interested in 60Hz and its close harmonics. Why would we give you anything but real instruments? That would make no sense. We use real A/D converters too! Amazing what good engineers can do, Andy.
It's called credibility. When you market AC power outlets claiming to "reduce midrange bloom" Power cords that have specific conductors for bass, midrange and treble? And you have yet to provide a technical explanation for those claims to spite my asking more than once. Hence my suspicion about the Power Plant. I want to see this "flat topping" And if I see it on the Power Plant scope, then by all means I will surely see it on a scope across the raw AC line!
Indeed you would see it on a bench scope as well. I hope you get the opportunity. Is the concept of flat topped AC waveforms unfamiliar to you?
The concept is hardly unfamiliar to me. What do you think amplifier clipping is? The question is how much 60hz sinewave clipping occurs in a typical residential power source and further how much energy, if any, is being lost. As usual in audiophile discussions you provide plenty of laymans theories but never any hard numbers to back it up. I would hope PS Audio owns at least one modern scope that can store and capture images. Show us some of the data you used when designing the PowerPlant. And of course once again you dodged the outlet and power cord question. You made the claims (you are the CEO), why can't you explain them in technical terms? How does an AC outlet reduce midrange bloom. Why would RF conductor technology applied to a 60hz power cord improve audio component treble response?
Oh goodness Andy. There's plenty of information available if you want to look. Your constant badgering and insults "I would hope PS Audio owns at least one modern scope that can store and capture images" are counter productive and tiring. We're a modern engineering company of 10 full time engineers with some of the best test equipment made. I haven't the time to invest in your education because your intent isn't to learn but to refute whatever I say. Life's too short for this. Here's what I suggest, if you're ever in Boulder you have an open invitation to visit our facilities where I will be happy to use real scopes and try and help you gain some insight. I do not have all the answers you currently seek, not in the form that would work for you. Some of my personal work is subjective in nature - something I realize drives you bonkers. Thanks for posting and viewing. You seem like a nice person and again, if you're in town, come on by. If for no other reason than to have a good laugh.
I think you dropped the ball on this one Paul.
How do you justify using such a power supply on your Sprout100?
Most important, is to have a well Earthed mains supply. Faulty equipment that does not go through Earth Leakage protection can cause havoc here, even if it is in your neighbors place. Most common by us would be a faulty water heater element.
Then the Neutral to Earth voltage must be low. Here by us the legal requirement is less than 10VAC but I would recommend not more that 2V for good audio. Then you can start looking at noise on the Live conductor but generally if the Earth and Neutral are good, most decent systems can filter out the noise on the Live. Balance line (XLR) input / outputs are much better at eliminating noise than unbalanced (RCA)
Fortunately I can check all this for myself but good luck finding an electrician who would care two bits.
whats Earth Leakage protection? My gear is on the ground on my dedicated 30 amp romex line to a 30 amp fuse whatchacallit in my house breaker box. I didnt hear any improvement but I havent A-B'd it though with a non dedicated line like a shared house outlet. For a long time i had the ground run out to an iron rod buried in the ground. Again no improvement really -- in fact a lightning surge came and destroyed alot of my stereo and nothing else in the house, and I dont understand why, but maybe the surge was attracted to the dedicated ground to the buried rod , as THE 'path of least resistance' for the surge to follow?
@@rd264 Hi.
Earth Leakage Protection Units (ELU or ELCB in othercountries) are a requirement in my country to protect people against electrocution. This is required because we run at 240V as opposed to 110V in your country.
An ELU is made to sniff out low Leakage currents (20mA or so) and isolated that part of the circuit if such a Leakage is detected.
Unfortunately an electronic system has to work together as a whole to be effective and safe. In your case, you effectively had your sound system between the external earth and the electrical system in your home. This is totally counter productive and unfortunately this matter is way to complex to clarify here. My recommendation is to befriend someone in the field or to do a lot of Googling.
Paul, I want to thank you for the information on "clean power." You were talking about how these AC Conditioning devices effect the higher frequencies. I've always had my amp (Parasound A51) connected to my $3000 AC conditioner (not from PS Audio), assuming the sound was better, and never questioned it again. But watching your video, I thought, "I'm going to plug the amp directly into the wall without the AC Conditioning." I'm here to say, "it sounds better!" Much better. Ugh ($3000?). The higher frequencies are where i notice the most difference, more pronounced, more extended, and everything seems more airy and refined. I was surprised. What have I been doing all this time?
So you wasted $3000, huh?
I'm not saying that I wasted $3000 as some kind of 100% statement. Initial impressions are rarely the final story, but can be useful. Time will tell.
Hi Paul. Since I am retired and on a fixed income (and have a modest, but adequate system), I can't afford expensive power conditioners. However, I noticed a big improvement after I added one of your "Noise Harvesters".
All i needed was a oversurge protector it worked fine, but when i bought a ups wow it was like night and day, so try it out yourself, it æ does not need to be an expensive investment at all btw.. try it out yourself and find out whats best for your house
Noise harvesters don't work. Lol.
PS Audio...Power-conditioner Sales Audio...lol
yup eddie van halen used a variac to get his sound from his guitar amps. voltage systems are used all the time for guitar amps at shows. so do recording studios
I strongly agree with Paul, power plants are awesome!
I invented a device that is used at the input and output of any Power conditioner, patent pending... This one is a game changer, no snake oil...
"Device adds energy / synergy characteristics to electronic audio and video devices, which result in a richer sound, with less noise and improved dynamics & timbre. In regards to video, there is an improvement with contrast levels and richer color enhancements, and overall cleaner images."
Stay tuned fellow audiophiles... Currently searching for a company to license from me, once this hits the shelves, it will cause controversy among the audiophile community. All cable manufactures will hate me, we're talking about a solid 10-20% quality improvement, not psychoacoustics...
don't forget your medication, wishing you all the best!
I had that idea long before you came upon it!
My lawyers will be contacting you.
I guess most people doubt this because they dont notice it and it really depends on how clean the power is that your using. I think a power supply on DAC makes sense - also optical digital audio (toslink) seems better than USB. Do I notice it? - I dont think so! Will I buy a good power strip with build in surge protection and power conditioner? -Yes! I think so. Its fundamental!?
Hamsters make great pets...
I bought a PS Audio Ultimate outlet in 2004 and am still using it in 2019, just love this little gem...
Paul you are great salesman .....
1. low Impedence makes difference.
2. make sine wave cleaner. (resistance usually cuases flat top of sine wave)
Clean Power is not that important as long the Power Supply inside your equipment have a good design and a good filtering and ripple clean up. You have to notice that digital equipment also creates noise by itself The individual transistors inside the chips create noise every time then turn on and off. The end product your amplifier needs is DC and as long your DC is constant and voltage is maintain steady and ripple free I think you are home. The end game in an amplifier circuit is the DC from it's own PS.
Then WHY do you sell a power conditioner? Is yours any different and doesn’t impact impedance?
It's not a power conditioner.
Bruno Rivademar really? Here. www.psaudio.com/product-category/power-conditioners/
AudiS4orce1 Hilarious.. Paul says clean power isnt a concern, but he sells one..
The idea that clean power makes an amplifier lose dynamics is just hilarious... 🤣🤣🤣🤣😂😂😂😂😂
It depends on the conditioner basic line filters can affect the impedance abit
Well said Paul.👍
Hi Paul, I appreciate your wise
advices and I find your way to tell very affordable to all of us.
After this brief introduction I want to say something. What I'm going to write along these lines don't pretend to be taken seriously because even I or me, sorry for my grammar althought it's not the subject of the matter here, well, the truth is that after 30 years of being actively, read:expending money, I'm not sure of anything related to the truth of the hi-end as I imagined when I was a novice full of illusion but empty of currency.
During those years, I could detect if I had cleaned the contacts or not, if my toslink fiver optic had been cleaned with alcohol or gel to wash dishes, I compulsively changed the polarity of the power plug and noticed differences but, Which one was better? It depended, even from my mood... I could go on and on and I'm so sure this same thing happens to a lot of audiophiliacs, sorry Steve Guttenberg for borrow...ing? Your catchy adjective ha ja ha, when one begin to behave like this, better check it out with a pro or stay away from some time of your beloved equipment, after a while, you will again start to enjoy the sound of your rig and the minute differences once were amazing, now are meaningless.
The real character of the sound system won't change by some 'trivial' actions one could try so if the sound in not to your likes, give it to a friend, he will be eternally grateful without ever suspicing you gave the leftovers 😂...etc...etc.
Nothing to see here. Move along folks...
If your rectifier diodes are only switching at the peaks of the sine-wave, then that means your bulk charge capacitors and transformer are doing their job well. In other words, your amplifier's power supply is keeping up with demand. No worries. If your DC rails are sagging, then your probably playing your stereo very loud. At lower volumes the AC supply impedance wouldn't be critical at all. So if your to the point where you are having AC supply problems, it seem to me it would be far more effective to run a larger dedicated AC circuit to the power amp/s from the circuit breaker panel. Maybe go one cable size larger too. Try #10awg copper. But a re-generator??? Really... how do you sleep at night?
Chris H Exactly.. If the voltage sags at its input, then there may well be a voltage drop in the circuit conductors. A larger conductor will solve the problem..
And to that point, at moderate volumes, voltage sag wouldn't be a problem and even when it does occur, the high CMRR of the amplifier insures that you won't hear it unless your dumb enough to let your amplifier clip. That's one of the things the feed back circuit addresses.
Chris H Well said!
I bought a power conditioner once, over a decade ago. It made ZERO difference, to audio, to video.
I returned it for a full refund.
I bought a power conditioner once. It made HUGH difference.
Would not want to do without EVER.
Paul P. I rather doubt a "HUGE" difference. Maybe some difference and most of that placebo. And a "difference" doesn't automatically mean an improvement. If I would have heard or seen an improvement I would have kept the conditioner in the system. My system as is, is about as clean as it gets when listening to music. Much more to be said of a quality XO in a speaker system than connecting to some line conditioner.
Big diference on audio digital and analog mixers,,,with furman noise is all gone,,,
Paul P the differences are always small, a little more depth, a little wider, better seperation, tighter bass, etc, but not huge. And in Milton's case no difference at all. It all depends on perception and the rest of the equipment. I dont notice the difference on my home stereo, medium to high end system, but on my stage piano I do notice the difference very easily, but that came with a small wall adapter, but I was glad that I could notice it, since the wall supply is $4.- and the power transformer, filtered, stabilized costed $400.-
MrTruth111 You are right, but all the small differences ( improvements) together make a HUGE difference, at least in perception :-))
It's obvious that clean power will make a difference, just not a big one, everyone in the comments needs to chill out and stop screaming about snake oil, this is real science but it's not gonna make a blind bit of difference to your 1990's boombox is it?
Arlen Moulton Then show us the science.. So far he hasn't and clearly knows little about power supplies..
Really? prove that I don't know what I'm talking about, prove that I haven't tested the output of some good quality PSU's with a scope.
I will, when I have access to my scope.
The golden ear has spoken: everyone but me are deaf
@@ArlenMoulton2 It's been 7 months since your last comment, have you had "access to your scope" yet and would be so kind to post the results? :D
Technics did there own Battery amp if any one remembers it , when they ruind the look of everything
As someone who is experimenting with tube amp design, raising the impedance of the power transformer DOES make a difference
I wonder if studying circuitry of neve preamps has any overlap.. well, they’re not tube but do tube amps for home audio have input/ output transformers?
I recently put two AC filters in series, daysy chained, and believed or not, the improvement was staggering, really hi-end, and all for less than 100 euros. I'm not saying that one can do this and expect a miracle but if all the parameters are being improved, acoustics, stands and rack included, we can reach places never dreamed possible within a constrained budget.
After tuning one's equipment, then, can we forget about formats, sources and meaningless disquisitions and be carried away by the music.
If the power supply in an electronic product designed to operate from a domestic mains supply needs another piece of kit to function properly in the presence of some noise, the power supply is not fit for purpose. Normal levels of noise a user could reasonably expect to see on the mains should be rejected by the PSU's input filters without difficulty. There is a valid argument for protecting equipment against transient surges and brown-outs and how much somebody wants to spend to achieve that is up to them.
I agree. Besides which all modern appliances which can create interference are fitted with filters anyway. This is entirely routine in both The US and The EU.
why go from ac to dc to ac and then in the amp from ac to dc??? better conditioner make dc and a dc amp???
great safari shorts dude
The power signal is probably the most important aspect of audio reproduction. Whatever source you are using, it is the incoming power signal that acts as the carrier signal in the modulation process. Just like AM radio (Amplitude Modulation), there is a carrier signal whose amplitude is controlled to represent another factor, in the case of AM Radio, the amplitude of a particular radio wave is modulated to represent frequency. In standard audio reproduction, it is the incoming power signal that gets modulated by varying its voltage to produce the final output signal. This means that however clean your incoming power signal is, your recording can only ever be as clean as the incoming power, because it is the incoming power that gets modulated to produce your final result. The power signal is your carrier signal in the modulation process. The better quality the carrier signal, the better the result.
It's either power or it is signal, can't be both
power is a signal, genius
@@vladg5216 No
So, the 60HZ AC power signal coming through your wall, you say it's not a "signal"? What is it, then? You're being pedantic. It is a signal. But even disregarding that sticking point (which you are wrong about), it still acts as the carrier signal in the modulation process. Perhaps you should read about modulation a little before being a pedant.
Vlad G No, it's not a "signal." It's a frequency.. A signal "carries" information from xmtr to rcvr.
Well, I guess that by using a 40kW on-line UPS for my house I probably get a rather low line impedance. Probably not as good as using such an UPS or a power regenerator just for the audio stuff, but better than what's coming from the city.
It is very complex to explain snake oil .
LOL
Indeed.. He's selling a product to correct potential voltage drop on an AC circuit.. The proper remedy is to simply increase the conductors of the circuit. Problem solved, no snake oil needed..
@@bradleysmith681 I believe he said he is primarily after lowering the impedance and voltage fluctuations are not that important for the sound.
you need to have faith....😇 its..... magic....
is battery cleaner than AC?
Depends on the inverter you're using
Unless you have equipment with a direct DC input port then it's a definite yes and in the worst case it's equal to AC
in car audio there is a belief that the cleaner the power going in (as in as little voltage drop as possible...) the cleaner the power going out. to a degree it kind of depends on the audio that youre running. lol home audio may not be as bothered by "dirty" power as much as some others. but i do know that dirty power can in some cases cause audio failures. 🙄 having an amp fail is never fun. ive had a couple fail. one was because of very crap power source.
Too funny.. A diode doesn't truly "switch".. It conducts.. Also, voltage has nothing to do with how often that the rectifier bridge conducts.. That is based on frequency.. Paul doesn't understand basic electronics.. Complete nonsense..
Hahahaha, seems like it doesn't it.

I've a feeling there's someone here who doesn't fully understand electronics. So that's basically true. I don't think that person is Paul though. Sometimes a little bit of knowledge can be a dangerous thing.
Well, a diode doesn't switch in the same sense as a mechanical switch. However, when used as a simple rectifier it is correct to use that term.
Again, once you got a clean DC voltage after filtering and regulation all is good. An amplifier or any other equipment doesn't have a mind of its own and doesn't work differently depending how the DC voltage is generated. If anyone is so concerned the best way to power your HiFi would be a big bank of deep cycle batteries backed with a big bank of huge low ESR capacitors and bypassing the power supply in each system.
I can assure you that I understand electronics quite well.. Again, I stand by what I said.. A "true" switch typical opens a circuit while a voltage is still applied to it.. This is the case for a mechanical switch, a relay, and often a transistor.. But this isn't really true for a diode.. It doesn't open the circuit while a voltage is applied.. Instead, it conducts (or doesn't) based on rising or dropping voltage. It is simply reacting to its voltage source.. Similiar terms, but there is a distinction.. And I agree about the rectification.. The rectification process itself is in essence a "filter." And anyway, most noise issues can be traced back to ground loops--hum at 60 Hz and buzz at harmonics.. None of the gimmics will solve this problem.. They are solved by good installation practices...
Clean power only matters to low voltage. Adequate capacitors and regulators on the primary and secondary on a power supply as well as metal covers to filter noise is good enough. Also, using LEDs with decoupling is very important as well. Diodes by themselves are very noisy, just drive by a traffic light with LEDs and listen to an am radio station. The buzz is obvious
are you saying that it does not matter at all for amplifiers and cd players and if so why? My integrated Naim XS2 for example is 70 watts/ch, it draws about 16 VA - 350VA [~ 16-140 watts]. My cd player draws 30 VA.
Interesting as always, I don't know why I haven't subscribed before 🤔
would love to see a video on the importance ( is any ) of a dedicated circuit for amps and such
Dual, standard car size, lead acid batteries in stereo woofer set.
I do notice our stereo sounds better late at night. I assume that's because all the neighbors are asleep and power consumption is down?
hifi noob 2018 it always does. Multiple issues here as always. My wild guess is it’s mostly because of less general noise at night.
An the reduction in noise level when everything in quiet permits or allows the listener to hear a greater dynamic range at the same spl, I've been thinking about this recently and I think that that cause of less noisy environment could be the reason of an improved audition. What would the results be in a rainy night ? I'd bet my farm, if I had one, that the sound wouldn't be so pure without being the electricity the cause, after all, everybody is in bed don't agree?
Salvador Rodenas it’s also less noise in power line not to mention psychoacoustics and biorithms. Concerts mostly held at nights in darkened rooms after warm up act for a reason.
wait but most grow rooms come on in the evening hours so....
Parallel filters are far superior to inline filters with coils. You do not lose dynamics.
clean power can is important as noise could cause malfunctions like for example could interfere with the stereo detection circuitry for the fm tuner causing the indicator to come on falsely (this is a problem on tv when they are broadcasting a sports event the crowd noise can falsely trigger the sap channel partially muting the rest of the signal.
it can also cause for example the stereo to turn off if the power button is one of them soft switches that triggers a transistorized latching system.
there is one place you can hear the difference as today's digital electric utility meters phoning home to report the power usage there is a interference that shows up as a square wave buzzing noise
you can see the interference as flickering of the cheap led lights that are simply a resistor capacitor dropper and a diode to convert to dc and no filtering capacitor.
oh boy, the expert commentators are out in full force today
yes, and there's a lot to be learned.....
Using a good audiograde power conditioner has improved my system about 20% It is like upgrading a major component. I can never go back.
Let's first create a problem so that we can then be seen to be creating a solution to the initial problem that need not be a problem at all then everyone will think we're so clever and believe everything we tell them.

Sure, but then your decision is made from ignorance given you have no actual experience with the product - experience that's free for anyone to acquire.
You can buy a perfectly decent UPS with true sine wave filtered outputs for around 1000 bucks or less and backed up for a decent amount of time too, not just 30 seconds.
