Great video once again.
Where I live I suffer from quiet a bit of DC on the mains which causes the transformers in my power amps and active sub to become saturated. This causes them to physically buzz and reduces their efficiency. I have installed simple DC blocking circuits to each of these components and that has almost entirely eliminated the buzz and has had a positive effect on sound quality, particularly dynamics.
An audiophile friend has attacked the problem from the other end. He went around his house systematically unplugging all of his electrical appliances whilst listening to his system in order to determine where the mains borne noise originated. Instead of plugging his hifi into mains conditioners he plugged his fridge and boiler into them to much greater effect.
what did you use for "simple dc blocking circuits" ?
You mentioned a surge protector in the same breath as the conditioner. My surge protector (non battery backup type) has saved my system from power spikes and burn out many times.
What are your thoughts on AVR (Automatics Voltage Regulators) like the APC ones that handle 1200 watts? Would they have a restrictive effect?
Hi Paul, I am a guitar player and play in different locations with my high school jazz band frequently. I have noticed that my tube amps seem to have issues with squealing (not EMI hum or ground loop noise) when I am at my school, but this has never happened when I have been playing at home. I have had to replace the preamp tubes in my amp because of this, however, this has happened multiple times with multiple amps. I know this is not a hi-fi question, but I love your videos and was wondering if you think purchasing a power conditioner such as a Furman could solve this? Thank you so much and I love learning about electronics and audio from all of your videos.
I was just in Chipotle's the other day and noticed the 3 way built in speakers where designed with tweeter on bottom and the woofer on the top. So unless you have a high end power conditioner for audio then just plug your gear straight into your grounded outlet?
Makes sense. Ive just plugged in some monitors into my usp, and the frequency line noise, can be heard clearly. When plugged directly to Ac outlet, sounds as should with the built in Amps in Monitors. I was curious if I should plug my Audio to any protectors for protection and especially a Subwoofer I have yet to make it compatible for my circuit breakers (2000watt Sunfire MarkII) since im having electrical shorts or Surges issues from my room being connected to with the water heater line for some odd reason, even with little appliances plugged in or wattage pulled, half the house will trip.
Im still trying to find a solution into having my Subwoofer connected with my Audio Speaker monitors, without having to trip my circuit breakers. Ive left my Subwoofers out to not risk the chance from being destroying with my surge issues . Any additional tips would be great! I almost went out to shop a Power Conditioner for audio, until i stumbled this video. Kind of figured in the back of my mind, of what you stated, with empiedence going against each other, it would be a waste of time and inconvenience?
Where I have my gear at there is only one wall outlet...but have 6 items to plug in. Intergrated amp, power amp, 2 subs, turntable, and cd player. If I dont want or need a conditioner...Can I use a power strip or a surge protector without worrying about losing any power to my amps or subwoofers?
Would a Monster Power HTS1000 (UK) restrict or improve audio? I do not have an extremely high end setup. I use a Yamaha MCR-N870 (mini system) Project Debut Carbon Evo, Schiit Mani, & 2 macbook pro's.
Not looking for a dispute, just wondering if using the Monster Unit would benefit the humble setup I have.
I've definitely noticed changes in audio quality from using noise filters, but what actually intrigues me more is that the lighted displays on my amp and dac actually change. In audio, people sometimes use terms like "blacker/deeper blacks" when referring to filtered power, but when I use a Shunyata PS8/Defender the actual LED screen on my DAC seems to have higher contrast and a slightly cooler quality of light.
Hows your Dectet power conditioner? you didn't speak about that in the video.
will a USA voltage power plant also help a step up European transformer or better off a power plant for the 230 voltage and add the step up before the power plant? - the scenario is for using European audio equipment here in the us.
whats about lag during gameplay due to some sort of disruptions due to power. when im at another house i dont get that its not the internet
Your old location had much better recording audio quality.
@D Master need dc conditioner from that dirty iphone battery

The utility transformer that supplies your home is an excellent low impedance source.. Will give you all the current you need at rated voltage.. No snake oil needed...
what about a Furman Elite-15 PF i (I use that). I was surprised about your answer.
I also use a Furman Elite-15 PF-i with 8 sources plugged in my Aragon 8008BB power amp, Aragon 18K pre-amp,a classic Sony CDP707 ESD,

You mention passive conditioner & UPS's (bad idea), but what about a ferroresonant line stabilizer/conditioner?
Thank you Paul. I find myself saying that frequently. Someday I hope to research the subject at hand with you BEFORE spending money on the new idea that has consumed my thoughts. 😊
Hi Paul, love your videos, but may I suggest getting a lavalier or shotgun mic for your videos? The sound would be so much better.
Did you ever design a soffit mounted 15" + horn speaker setup for Chipotle? I have a particular memory of walking into a Chipotle and being surprised by music that sounded great. I was legitimately confused at first!
I think the key thing to keep in mind is what is that passive power conditioner really rated for. The specs on the box are probably just what they don't want you to go over to prevent a meltdown - aka lawyer ointment.
My system amp is a heavily modified Hafler d220 that has 22,000uf filter caps in it so it draws hefty power slugs off the line. I do use a power filter but it's a surplus military model that is rated at 40 amps RMS and I notice no degradation of the sound or power output with it in the system. That said I'm 70 years old and my hearing may not be as good as yours is, if you have any doubts plug large power amps in BEFORE any line filter. I would suggest dedicated 20A outlets for your audio equipment to make sure your getting good power for your system.
I also use a 30 amp shielded isolation transformer to feed my audio system (240v primary and 124v secondary), that sucker weighs about 100 pounds - it's hanging from the floor joists in the cellar.
Thanks for your video, can one measure the effects of power conditions? For companies who invest huge amounts in their amplifier power supplies, do they really encourage products like these? All that care and effort, for a user to then put in a huge variable that will affect/even negate all of the testing and measurements of the amp before it left the factory. Hard to imagine. I certainly have heard some companies that specifically ask users not to plug their amps into these conditioners. I’ve tried a few of the high end ones (not yours though!) and am unconvinced. well designed amplifiers put so much effort into the power supply. Why muck around with it.
What do you think of furman power conditioning?
Dont buy the entry level stuff like merit from furman
@@callofdutybigpapi Thank You.
I would like to see real data with graphs showing this because this video has a lot of physic principles halfy explained and made to fit a product.
@@jameschristiantaylor123 Actually Harman proved with around 86% accuracy what people liked in Speakers and they did with with a double blind test. You might not like the science but it’s true regardless of whether you like the results of not. Read the book by Dr. Floyd Toole and you will learn a lot. Paul would never read but you definitely should
How can you tell if a power conditioner is limiting the power? Is there some way to measure?
It's not, trust me..... Paul never explains anything with any type of research or some type of solidified response. I want to see math, not opinions. I am an EE and a lot of what Paul says is his opinion, please take it with a grain of salt. I'm sure Paul will hate me now, but I'm not in the habit of making friends....
Was thinking about buying a pure sine wave inverter for my equipment. Not anymore, but on the other hand I will continue to use the Furman power conditioner.
Why don't you think a pure sine wave inverter for equipment is a good idea? Please explain in your words.
I'm thinking of doing the same for my equipment.
Improved power handling has been on my list for quite some time. Without placing you in the awkward position of product promotion, as some people watching your videos appear to be sensitive to, how is your Dectet power conditioner resolving the issues you've described? The P5's price is out of reach for me.
Fascinating topic. I believe that the camera guys audio was plugged in to one of those UPS Paul was referring to...just a guess though. Enjoyed the topic anyway!
Good advice. Thanks.
My problem with power plant and I have tried a few they do nothing for EMI
Great topic, worth a remake.
Another good video Paul well done.... No out going music today why ?..... Think about going back to the old location Paul if the acoustics are better there, but do the segment anywhere so long as the acoustics are good... I asked a question for the "Ask Paul part of this You tube channel almost 2 and half month's and still I have not gotten a response ?...
Snake oil, just like speaker wire (cable?). My question to speaker cable people ($500/ft.), if your cable is coloring the sound in such a good way, how much do I run? A little or a lot???
I don't think it's the cable but the terminals you use at the ends at the cable that lowers the total impedance of the cable itself
@Larry Niles I was just fucking with you jackasses
@@bjornahh87 senseless statement if I ever heard one
You're right about speaker wire. Copper is copper. The variable is gauge. The snake oil BS speaker wire stuff is laughable.
Is that a real Jasper Johns in the background or a repro?
This video needs a power conditioner. Is there a fountain in the office? Lol
I’ve learned something day after day I watch your videos, thanks, but I can’t help noticing that’s a huge classic RCA Victor Records Dog you have there, 👍
Why get surge protection and line conditioning? My down the street neighbor hired an incompetent election to wire his house and ended up blowing out the entire block, 16 houses including mine. I had to replace dam near everything in my house, heater, micro wave, TV, stereo equipment, oven. Hard to believe most of what I mentioned was turned off at the time! I'm now in the process of having the power service to my house upgraded and fortunately it has a whole house surge protector installed, but I also made the decision to include additional layers of protection. I'm all for getting the best sound possible but I'm still going to protect my investment.
UPS running a pa system.. why?
Line-interactive UPS will not generate sinewave signal unless using the battery when the power is out. Your will not encounter that generated signal from UPS if your power is on.
What a great resource are these videos , thank you for making my system sound better , I should be paying $ for this.
I have a different question for you. I own a small sound/lighting company, providing sound and lights for live entertainment on stage for small to medium venues. I also do DJ/KJ. One event I am tasked to do every year at a local county fair, is set up a sound system for a demolition derby arena. There is no permanent electric power source set up for this event, requiring me to utilize the 120volt tap on a crank-up light plant generator. These generators vary greatly in their quality and usually do not provide a constant voltage output, even to the 120 volt recepticle. I recently had this experience. My system runs through a rack-mount surge protector/line conditioner which has a digital volt meter. When I plugged into the generator, the output voltage going to my system was sitting at 183 volts. I made the mistake of having my Behringer NU4/6000, 4 channel power amplifier plugged into the surge protector. I heard a pop and channels C & D went dead. I shut down the system and unplugged. They switched out this generator for another unit and I plugged into it. The output voltage to the 120 volt tap was reading 159 volts. (Actually fluctuating between 159 volts clear up to 173 volts. Taking a chance, I turned on my system. The Behringer amp was still working on channels A & B only. The system did tolerate it. Later, after dark, they switched on the lights on the light plant. After several minutes, the output voltage went down and stabilized at 124 volts. My question is this: Is there any kind of device that I can use to not only protect my system from this kind of voltage problem; but also be able to regulate the voltage myself so that this doesn't happen again?
I'm looking at some of the Furman pro rack gear, and they seem like they would protect you from both over and under voltage scenarios. The products I'm looking at would protect your gear if plugged into, say, 140+ volts, but most units I'm looking at won't regulate the voltage. They simply disconnect when the situation is detected so your gear is protected. However, the show is over at that point.
I'm not sure what price you'd pay for voltage regulation as that was outside my scope or needs. They exist but are orders magnitude more expensive than the $200-$400 rack gear that I'm referring to.
Most UPS's, including ones that deliver pure sine wave output, are "standby" UPS's.
Meaning, the UPS does not generate anything. It only passes along the power from your wall's outlet (that is, unless it also does power conditioning, then that can be an issue).
The only time the type of "wave" that a standby UPS puts out matters, is when the power goes out (or drops below a triggering threshold for your UPS). Then, the UPS will switch to its batteries, and will deliver a square wave, or stepped sine wave, or sine wave, to your equipment (the type of wave is not configurable -- so you have to purchase the type of UPS that is best for your needs and your budget). But if your power is so bad that your UPS needs to switch to its battery (or if your power goes out), then that is probably better to feed your equipment any type of power wave than having your equipment suddenly turn off, or having your equipment starve for power (if the power from your outlet drops too low).
There are "on-line" UPS's that 100% of the time do double conversion of the power. These are the most expensive class of UPS's, and do the best job, and are the least efficient.
They turn your wall outlet's power from AC to DC, and then turn that DC to AC and feed that newly generated AC to your connected equipment (this double conversion process will cost you some electricity, as that double conversion uses some electricity to perform that function). Although that provides the cleanest power, with zero interruption from power issues, it might not feed a stereo the best power (as Paul explained).
An on-line UPS is typically used where the connected equipment must have perfect power 100% of the time.
As quickly as a standby UPS can switch to its batteries, it does still take time. Most equipment will not be affected by those milliseconds it took for the UPS to switch to its batteries. But if those milliseconds are an issue, then an on-line UPS is the solution.
With an on-line UPS, then no matter what is going on with the power from your electric company, not matter how erratic, the power being delivered to your equipment will never see it. That equipment will always be getting freshly generated power from the on-line UPS.
Note that an on-line UPS is never silent. They can be very quiet. But never silent. They make noise because they are always doing double conversions of your power. Apparently, that cannot be accomplished with complete silence. Perhaps it is their cooling fan that contributes to the whisper of noise? I just know that some noise is always present.
Cheers!
Hey , my dad asked me what's the best device to protect his audio equipment from lightning strikes , surges and power outages. I was going to reccomend a ups..can you tell in layman's terms what to buy ? it's like 8 devices amps etc .
@@RicardoPower You did not mention a price range or budget. You did mention that your dad wants the "best".
For protection against all 9 types of power issues (there are 9), then one of the UPS models that begins with the number "9" will offer top tier protection of equipment that is connected to it.
www.eaton.com/us/en-us/products/backup-power-ups-surge-it-power-distribution/backup-power-ups.html
However, the above is not marketed for audiophiles.
Yes, it will ensure a long life for your connected equipment, and will ensure that no electrical issues ever makes it to the connect equipment. But I have no idea what such a UPS will do in terms of affecting the sound quality of the connected equipment. It offers the best protection. But like adding armor to your car, what will that do to its performance? Maybe such a UPS will be great for a stereo? I never saw a review for this purpose, and I am not going to spend thousands to find out.
Audioquest's Niagara 7000 is the best power conditioner that I know of, and it will suppress electrical spikes and surges (although probably not as good as a "9" series Eaton UPS).
www.audioquest.com/ac-power/ac-power-conditioners/niagara-series/niagara-7000
Also note that the Niagara 7000 will do nothing if the power goes out (whereas the UPS will keep the power flowing, via its batteries, during outages).
The advantage of the Niagara 7000 is that it is designed specifically for audio gear, and will allow your stereo to sound as good as it can sound.
Both the UPS option and the Niagara option are expensive. But you wanted the "best".
Cheers!
@@NoEgg4u Again thank you . I'm operating from the Carribean , so I will try to source the Eaton ups .Really appreciate the help , thank you .
@@RicardoPower Those 9-series UPSs are expensive. Their top models can run a small town, and cost as much as the town (probably several hundred thousand dollars).
I have not checked for a while, but even their least expensive 9-series model is probably $1,000 - $2,000. And you must ensure that it can handle the full load of the equipment that will be plugged into it. For example, they could have a model that offers top tier protection, but can handle only 500 watts. That would be a great choice for protecting a home computer, but it will not be able to handle the load of a powerful stereo system.
If you want the best sound quality, and still really good power protection (against everything except low power conditions and blackouts), then I suggest you go for the Audioquest Niagara. It is an amazing product.
And to really reap the benefits of it, all connected audio gear should be fitted with Audioquest power cables. Any of their power cables will likely be better than what comes with your audio equipment, and their better power cables will be far superior to what comes with audio equipment, and will have a whopper of a price tag.
Hello!
Well you look like a person who really knows what he's talking about. I've been searching for a valid comment on so many videos but I've finally found out someone who really knows stuff.
I was thinking to buy a APC 1kVA double conversion online UPS for audio equipment. It would keep the voltage and frequency stable. They say it's pure sine wave at the output. Do you think it's good? I only need to power my PC, USB audio interface and studio monitor speakers from the UPS. Purpose is, I want to get best audio sound using plugins on my computer for playing guitar. Will a Online Double conversion help me to get rid of bad AC power and noise coming from the mains?
My main purpose is, I want to play electric guitar and get best audio results. I maybe using a PC to play guitar with audio plugins or I may even connect a separate guitar amplifier to UPS. I only need 400~500 watts max.
I have noticed too much noise being introduced in my computer and my guitar sounding very muffled when I've plugged everything straight into the wall or a cheaper backup UPS.
This makes me believe that the electricity quality I'm getting in my house is very very poor. Because the plugins on my computer are not sounding anywhere close to how it must sound.
Also if someone switches on a washing machine in other room, then noise is introduced in my guitar playing and computer screen flutters (sometimes goes off for 1~2 seconds). Even if someone switches on a ceiling fan, then my computer acts weird. I believe this is AC noise, but not sure.
Will a online UPS who does double conversion (I'm looking at APC 1kVA) work miracles? Will I get absolutely clean power?
Also note, There is huge voltage fluctuation in my area. Sometimes it's 230V, suddenly it's 248V, then it's 255V, then it's 235V and so on, throughout the day.
I think double conversion ups will give steady voltage. But will it also clean up the AC mains power?
Thanks a lot!
So the best thing to do of Possible is Build a Dedicated Room Wired on it's Own Circuit Separated from Reat of the Home to Run High End Audio Equipment. Possibly Hospital Grade Outlets would make best sense
Shunyata Research addresses these concerns, SOTA.
I have enjoyed your videos for a while now. But I'm concerned about the "stepped wave" you mentioned. Surely we all know that those waves are not actually stepped, that is just an easier way of marking points along the waves journey. A bit like a dot-to-dot.
Modified sine wave inverters are very stepped. There is no filtering done to smooth them out. Hook them up to a scope and look for yourself.
No, Paul is correct. The output of a so-called "modified sine wave" inverter has only 3 voltage levels present: 0, +170, and -170 V. It is very distinctly stepped. The only reason it isn't called "square wave" is that a square wave would have only two voltages, +120 and -120. By adding the zero voltage portion of the waveform, and increasing the non-zero portion to 170 V, you get a waveform that's 170 V peak just like line voltage, for capacitor-input power supplies, while the RMS voltage is 120 V for resistive loads like light bulbs. Just look at the output of a UPS on a scope when the input is unplugged (to force the inverter to run).
Sine-wave inverters do not have a smooth sine output either, but they are a lot closer to sine. They use PWM to produce an overall sine shape.
Guys..... Your typical wall socket voltage is what, 120VAC. Your typical current draw can be up to 15amps. So, how much is this equipment drawing that something is going to limit it like a power conditioner? Can you back this up with any factual information besides your opinion Paul? If your equipment is drawing more than 15 amps of current, sound like you need more power to begin with. If a power conditioner is some how "limiting" the provided power to the equipment, sounds like it was defective to begin with, or 15 amps is simply not enough for said equipment. Please elaborate on this.....
Howdy.
Rectification in the amp. generates a lot of current harmonics. The power supply transformer also generates some inductive current which is the same as the transformer magnetization. The harmonics and the magnetization all end up as reactive power. They lower the power factor.
I agree that UPS.s do not handle reactive currents very well. And I presume that PS Audio has had this in mind designing power plants resulting in superior performance.
I wonder if the ancient technology of using two syncronous induction machines would be a feasable way, running one as a motor driving the other as a generator, to provide low impedance power ?
Mains voltage fluctuations do not cause axle speed variations in syncronous motors as they do with regular induction motors. Fluctuations cause only a very small change in axle angle relative to the motor magnetic field. I believe the generator can easily handle the reactive currents coming from the amp.
Regards.
What a pile of horse shit. Fucking clown
Furman Power works great with my Audio Components especially with PS Audio power cables
All businesses should have at least two women at the front desk reception area, both women should be experienced tickle fight practitioners and all businesses should encourage excessive giggling while the tickle fighting is in progress.
This is only my viewpoint. Good equipment should have appropriate immunity to mains imperfections. Its an integral part of audio design to deal with typical power fluctations and noise.
Its not really fun to spend time on power supply design. Good circuit topology and layout will tolerate quite a significant amount of power issues.
A large portion of money often goes into the power supply of a unit and that is were cost cutting often takes place.
An oversized toroidal transfomer is not a guarantee that the power supply is as good as it can be. Maybe one should be able to buy a power amp output stage only chassis and add power supplies of different grades, maybe based on amplifier type and speaker impedance.
I can imagine adding chokes and other devices that can create magnetic fields can interfere with sensitive circuits if in the same chassis.
I think there is so many people that can’t hear and justify the snake oil that they won’t pay a premium if the enhancements are included as a standard. Reminds me a bit of special edition models of manufacturers.
The noise filter is destroying the sound - yikes!

And here I am unable to tell the difference between a $3000 amplifier and a $30 000 amplifier driving my speakers... (Magnepan 1.7 which should be enough to be considered "resolving".)
Agreed. Higher price does not always equal better sound. It may however give you a better looking fancy nice-fi unit in your home. And I don't say there isn't such a thing but it is rarer than ever. I have the same experience with most TOTL units. I think it has a lot to do with how electronics evolved. Now we can buy something for 2-3000USD that was 3-4 times more expensive 2 decades ago (if at all available). Speakers did not change all that much but are available for less. This is truly a great time for audiophiles.
Kacper Uminski - You either have great power supply coming to your house or have poor ears? This is a light hearted jab. No personal offence intended. Don’t take it too seriously.
The vegan thread was funny; comments are a real hoot sometimes. I guess he didn’t see the ones where you were doing your answers while hiking.
YOU LOVE TO TALK
Without power conditioning, already built in by the amp designers, the equipment simply wouldn't work. Additionally, even low cost gear has an RF filter in the form of a common mode ferrite choke/inductor and associated capacitors. There's no need to add any more power conditioning and those who insist it is necessary are audiophools or trying to extract money from them. Any subjective noticeable difference is bound to be psychosomatic.
I don't use anything on my stereo or home theater but there isnt a working musician I know that doesn't have some kind of power solution in their rack. It's an absolute necessity when traveling and plugging into god knows what and I know that from experience. You can damage your gear without it.
@@DanielC__ the power conditioning devices that connect in parallel with the mains supply do nothing at all. With travelling musicians and spiky mains from, say, a generator, to make any difference, the conditioning components will need to be in series with both the phase and neutral. The varistors can only clean up the power supply a limited number of surge events before they fail. PWR conditioners, if designed correctly, will have varistors across the supply. What's happening is the additional varistors in the conditioner are substituting the task of the failed ones inside the equipment. Eventually, the ones in the conditioner will, eventually, fail, too. The issue here is predicting when these failures occur and arrange for the all the varistors in all of the equipment to be replaced.
i seen one of his and it was 9999 lol the unit is ugly i can get a mcintosh for around 6 k used when i decide to not be a miser ill go with the mac
I get attention to ps audio yesterday. I viewed the products at the website. And I was desperately disappointed when I see the back panel of the product. In particular the Stellar M700.
They look cheap because to the fact that they are black with white print, the heads of the screws lap and can be seen. The power switches are very cheap types snap ins.
The input jacks are scrappy Chinese standard components. Should be better for this price range.
All over it looks like all other dirt cheap products on the market.
I would not expect such a bad design of a back panel in this class PS would be.
From my point of view it is a bad idea to have a design like this. Mostly In the dark behind of a rack this becomes a difficult job due to the dark design.
A design process does not end at the top cover.
You could and should do it better.
@Larry Niles you're full of shit. Break down their products and you can source every part for 10-15% of what they charge. It's snake oil BS
With all due respect sir, if the small changes on the AC side do have an effect on audio quality, then the DC power supply built into the amp is poorly designed. The DC power supply should be designed to provide enough stable power to the amp, regardless of noise on the AC side. If the ac side doesn’t provide enough power at all, that can’t be solved by another device in the chain. If high frequency or impedance on the AC side have an effect on the sound, fixing the power supply inside the amp is way easier than putting some snakeoil device in the chain.
Agreed. Mr. McGowan is once again blowing smoke in a weak attempt to draw distinctions between his products and competing products. By virtue of the enormous capacitive storage connected to supply rails in most modern amplifier output stages, tiny variations in voltage stretched over short time spans have no audible and virtually no measurable effect on the output. The only susceptibility to noise is with poorly designed amps that have gain stage inputs which aren't properly isolated from noise sources whether those sources are external or lie within the amplifier circuitry itself. McGowan doesn't want to tell the truth about "power conditioner" or "high end" cable sellers because they are considered "partners" in the industry. The trade magazines that derive a profit from propping them up also prop up PS Audio.
What is with this? Does it not make sense to you that there are signals present from the lines from appliance motors and various things in the house? Should all the filters come inside the amp from the manufacturer? Open your mind , your knowledge base is limited.
jeremy whittler the ac/dc conversion that is performed is by definition a filter inside the amp. After that, you do need all kinds of circuitry to make sure any sudden power requirements of an amp can be met. The amp needs DC after all. If you have a grinder that is not capable of coping with the different sized of grains in nature, you would not pre-grind your wheat before feeding it. You would buy a grinder that does the job.
Same thing here: treating the AC to get a better DC is admitting your AC/DC converter is not good enough. And it’s wasteful.
Wrong - they are not ALL "unregulated simple AC bridge, capacitor affairs that are quite sensitive to line voltage noise and changes". You should know better than to speak in totally ERRONEOUS generalizations. For those who actually want to learn from an ACTUAL expert, you can read here: www.eetimes.com/document.asp?doc_id=1278195
I would have to agree, this is bordering on the proverbial snake oil
I dunno, that dog looks fake to me
Because it's not a dog !
if you lived in austrlia you view would be totally different we are supposed to be running on 230 volts but it fluctuates that much ie 215 to 250 volts in 1 day no voltage reg and conditioner and your gear will be history
It's like that everywhere. The guarantee is typically 10% around the specified voltage. So your tolerance would be from 207V to 253V.
@@timharig i had a pair of golden ear triton 2s blew the amps 5 times in 4 years
Sound quality is bad
Anybody who's anybody is running their system off DC power anyway.
Terrible audio on this clip , which is very ironic when it comes from PS audio
snake oil!!
PS stands for poor sound quality? For a non native speaker it is difficult to follow. Did you know that Audio is more important than Video?
Once again absolute BS from this guy to sell his products. This like many of his videos make me laugh out loud. SNAKE OIL
Paul this audio sounds like trash. Come on you can do better than this.
Why don't you focus on getting rid of that disgusting roll of fat around your stomach instead of worrying about power amps? You are in horrible physical condition. Stop eating garbage and hit the gym.
Vegetarian is not enough. You need a low fat, plant based vegan diet. Fish and dairy is the killer for most vegetarians and with all the hormones, this makes it impossible to be lean. Read the Starch solution or Forks over knives and get a subscription to beachbodyondemand.com. This way you can do great workouts at home. I have done all this myself and look 20 years younger than I am.
You need resistance training. Get yourself a set of powerblocks or Bowflex adjustable dumbells, both from Amazon 50 lb sets are fine and then sign up for Beach body and do the resistance programs. That's the best way to shape up. They have cardio programs there too. Avoid cheese, all vegetable oils, and all dairy products. That way you can live another 30 years. I'm 61, but no one believes I look more than 40.
That was very rude, totally unacceptable statement.
what an idiot you are ...go eat your spinach popeye and get lost....paul could run laps around your old broke down ass....keep up the good work paul !
Leading a conversation with “disgusting” is awfully rude. Apparently your diet has done nothing to improve your social skills.
