A good amplifier circuit design is a good design regardless of class. All that matters is what sounds good to you, with your rig, in your room, with your ears!
Lol. You sound like a robot. So what's your plan ? Try everything each week for 10 years until you spend 50K+ and lose 20K on resale to get your room and gear matched ?? Lol go for it bro... 🤣 smart people hire professionals.
You are right .... why would anyone want a highly inefficient and antiquated class A amp ? If you happen to get in a old Threshold or Accuphase class A amp let me know .... I will take that clunker off your hands for you.
I'm in HiFi since 1970 and had all kinds of systems class A class A /B Integrated, separate units, etc. and finally, I went to class D and never looked back . Runs cool and has precise control of the speakers, modern design& upgradable, and avoids "cable salad" with integrated without spending a fortune but as always needs speaker matching. We are all aware, not every amp blends well into every speaker. Class D is the future that is for sure. Looking for absolute sound is a lost cause and I talk from experience of over 53 years. Good music recorded will sound good on most systems. We have all been on a Hi-Fi journey where sometimes the equipment was more important than the music which in my opinion is the wrong path. Going back to music is the real deal and one has not had to spend enormous money to get that experience.
Every class D I have tried/owned just doesn't seem to image like class A, A/B or have that body/character in the mids/highs. They all sounded good tonally, just leaves me wanting those characteristics that make class a good class A or A/B appealing. The closest I have come to that sound is the Rogue audio dragon and the PS audio Steller M1200 series was a close 2nd. But again they just didn't image well and I always felt something was missing something. For now Ill keep my Pass that draws 700 watts at idle....
The NAD M23 base on the latest Purifi Eigentakt Class D technology can be worth a demo. In fact thee is a demo on youtube between this NAD and a Pass Labs amp. Pass Labs has the edge on soundstage size, M23 wins on bass control.
@@connorduke4619 I believe that, my XA60.8 are slightly fluffy with the bass, it's good bass but every class D I tried was tighter, faster. Thanks for the suggestion, I will have to take a look at those.
Spot on observations - I’m also interested that in your opinion you now think that a well designed class A/B wipes the floor with Class A. I’ll check out Jeff Rowland.
Altec Lansing was my favorite back in the day, best sounding speakers I used back then. Wish they were still around. Class D..... is it full bridge or half bridge? Full bridge old, half bridge new...ish.
Very interesting. I have a cheap Chinese class A tube amp and a nice Hegel class AB. The Hegel is running a pair of Maggies and the tube amp is driving low end Klipsches. Both are great pairings and and I love ‘em both. But that little tube amp can’t handle the Maggies at all.
Nope. JR is not a newest technology adopter like many followers. AGD pioneered GaN, many followed, JR is actually going back to AB as all the lemmings jump over the cliff. Class D is a double edged sword.
Class A all the way 👏 Vintage sound 👌 🙌 👏 😎 ✨️ 😀 I like all kinds of amp classifications but there is always something about that Vintage Hifi tone, even if it's inefficient. Long live HiFi!!!!!!!
Faster Switching with best possible Shielding has less time to Distort! Van Allen Radiation Belt still puzzles me with antiquated Switching! Did we really travel in Space with Class A Switching at 25% Efficiency! 😎✌
Amps got more efficient, speakers less efficient. Right now the overwhelming majority of speakers sold today are 0.1-1% efficient... so any hailing the efficiency of amps is just BS if you conveniently forget that the 'modern, advanced' speaker is a room heater for 99% or more and makes a little bit of sound as a side gig.
I have and Ashley FET 1000m in storage right now. Used to use that for live reinforcement. It sounds soooo goood and weighs soooooo much. Hate to part with it. Now using a 5lb class D amp ... for my live bass guitar rig and my home stereo amp. Wild times and old bones....lol
@@OCDHIFiGuy I tried a Demeter rig YEARS ago and it was the best bass amp i have ever played through. It was not Class D however. I am just using a Fender Rumble 500 watt D head. Same one that the bass player for Joe Russos Almost Dead uses. Killer amp. 5lbs,powerful,has been reliable and relatively VERY inexpensive.
@@OCDHIFiGuy I had a Peachtree Nova 300. It uses the ice power module. I was using the built in DAC at first but then got a Sabaj A20D (2022 model) which to my ears sounded better but the sound still had that dry character to it.
@@OCDHIFiGuy Thank you for the tips I’d love to try those someday. For now I’ll stick to my A/B Denon PMA-A110 as it has added that warmth and body that the class D wasn’t giving me. Class D certainly has its advantages when it comes to efficiency and fast transient response. For reference I use a modest pair of Focal Chora 826.
As an engineer, I actually understand how the signal is generated by these amplifiers. Class D by all standards, is inferior and always will be inferior to a Class A. The Class H takes Class A circuitry, and uses a PWM power supply to make it 80+ percent efficient. It is by all means the overall best current generation setup. I believe the new Benchmark amplifiers are Class H... 90 percent efficiency, and they are exceptional.
I recently considered purchasing a refurbed Classe DR VHC to drive my Maggie’s. I think 25 w into class A but shit loads of current. Lots of these old amps sounded quite good but common sense says why? Can’t carry it into my listening cave. Extremely inefficient and well then there’s the age and repairs. Kinda sounds like owning a vintage bike. Combustion engine is archaic tech as is speaker, amplifier, turntable tech but we continue to squeeze that lemon. Better materials, tolerances, computer models etc. Ride or listen to what gives you a giggle but keep moving forward with an open and analytical mind. Then go listen to Live music with friends, drink some Tequila, learn to play a guitar …. a bunch of boxes make an entertainment center not an experience.
@@OCDHIFiGuy “Copious second harmonic distortion“ isn’t the case at all with my Luxman L-590AxII. Measurements back this up. The micro and macro dynamics are stellar, if the speaker doesn’t soak them up with an overbuilt/over-damped enclosure.
@@van94weightlossjourney I think T has been rendered "non viable" for Audio standards in terms of strength. They do sound good in some cases but are easy to blow up. Otherwise we would have seen them catch on. Good point however.
yep, buying a Class A/AB amp in 2022 is ridiculous, dinosaur technology, Class D is the future, Hypex/Purifi amps are state of the art, the research and engineering by the likes of Bruno Putzy cant be ignored by "Audiophiles" any more
It's pretty true, but it's a precise science. Class D is a real bitch to get right. It's easy to make them dry and analytical. A magic trick to keep them accurate as well as organic and nice to listen to. Even though Class A is old ass tech, heavy and hot, it still sounds wonderful.
My Tube, Single Ended, Class A, Output Transformer Less, Minibeast amp is 3.5% efficient, runs 3, JJ Electronics, EL 509's/channel and into 16 Ohms, outputs 7 Watts, @ 8 Ohms, 4 Watts. Below 8 Ohms, forget it. Currently driving Stax earspeakers, but I have a pair of Lowther DX 65's @ 15 Ohms, and Raal 150-15D's @ 16 Ohms, to employ an active xover to drive the Lowthers above 200 Hz and a passive single Reliable Cap/CFAC Inductor, based passive xover, for the Raals, at a frequency, yet to be determined. As an example of the inefficiency of the above amp, the same Kit Manufacturer had a Transformer Coupled Tube amp kit that used just 2 of the EL 509's, in a Class AB, push-pull topology, that output 150 Watts/channel into 8 Ohms. But for the meager cost of electricity, I'll gladly accept the tradeoff of very lower power for sound quality. Hopefully, the newly realized Cubic Boron Arsenide semiconductor material with vastly increased Hole mobility vs Silicon, will yield superior Transistors and a new Class of amplification.
Got any more of what you snorted dude ? Lol. I've got Feastrex Field coils with Tungar Power supplies. 3 pairs of monoblock 300B amps. 2 pairs of 845 monos, 1 pair of GM100 monos, 1 pair of GM70 monos, OTL x 2...on and on. It's for fun. SS is for business.
@@OCDHIFiGuy Why aren't valves for, "Business"? Your customers deserve, "Fun", too. Bet my hardware cost me a tiny fraction of what you paid for your truly amazing hardware. Those GM70's are incredible space heaters or what, huh? What OTL's are you using? I'm also using an OTL into 4 Ohms that delivers 25 watts driving a system built around Dave Graebener's, RD 57 a 54 inch long by 2 inch wide, push-pull, planar magnetic, originally built for Boeing's Noise Analysis Labs. Cost me just over a grand for the pair. The second generation iteration, the RD 75 used to be available from Parts Express for 1400 bucks a pair, when Dave was still alive. Now, We can't buy them, as they are used for the midrange in the Genesis Prime, from Genesis Advanced Technologies, for about 400,000 bucks/pair. That is the current, abysmal, state of the, "Business". Personally, I still have more fun with my left handed Strat, and making music than listening to the, "Music", created Today. Blackmore, Paige, Zappa, etc., etc. I'll listen to them first, for pure fun and learn. I enjoy Your channel, greatly, but the cost of commercial gear is depressing for those that can't wield a soldering iron, use a table saw, or can't figure out how to use a multimeter.
@@scottwolf8633 I'm not sure why people ASSUME so much. Do you feel your impulsive story of what I'm talking about is actually correct because it's through your personal perception ? I sell both Tube and SS. I carry only brands and models I consider a breakthrough on at least one charachteristic. To plea cost is to no avail. I'm talking about circuit design. Perhaps I misunderstood your post as being a "big dicking" of your rig and its superiority. I feel bad now as you don't know the GM70 are the small tubes nowhere near the heat output of the near 100 times larger GM100 so I'll ease back on my defense. I know well about BG. I've got the LA 600s plus the center inside my walls for theater duty. Roughly 35K of BG Inwalls I dont use. I've got 4 of the 2 inch wide 48 inchers or whatever they are. (Not 56) I'm familiar with Wisdom Audio. That's more my speed. BG is great for DIY projects. SS is for business means for Analysis of what's upstream. SS is far more accurate with much faster transient response than tubes. Period. It's business only. No romantic floating down the buttery River of honey laden cream that SET produces.
@@OCDHIFiGuy It's all good Bro. No offense was taken. For me, ego destroys the learning process, and that is what motivates me, learning. I was building solid state, Class A Topology from an article published in the Audio Amateur, The Lang Amp. What motivated me was a quote from Nelson Pass about it being the most advanced and elegant design yet published and that included His Own work, as He was a contributing editor. Nelson is extremely humble. I used some of His papers and some of what J. Peter Moncrieff wrote in His Journals to modify the power supply. Built it so I could take it apart very easily. To change out circuit boards and built out two iterations of said boards with really cheap circuit elements and also boutique, very expensive, aerospace grade, circuit elements. Couldn't detect a difference between the two as I listened for two years switching out the boards. Taught me a lot, that it IS the topology. So, I wholeheartedly agree it IS about the design. I am extremely familiar with solid state, but then in the same Publication a few years later, a book was advertised/published about Valve OTL's from an EE who received a patent for his Topology. I was intrigued and bought the book. I'm not an EE, my first undergrad in Math/CS. Read through it several Times and then took a gamble and bought His T-16 monoblocs. I've stopped building solid state because of His utilization of valves sans Output transformer, it just works for me. Grew up in a household with a baby grand, Steinway and played strings most of my life and nothing has come as close to the timbrel accuracy. My T-16 with 60 watts @16 Ohms with a power bandwidth from 5 Hz to 60 KHz, will power two of Ted Jordan's JX 150 NG's/channel in 12 foot long waveguides. The Minibeast I own has a power bandwidth from 10Hz-100KHz. Extremely analytical and FAST. His latest version of the Minibeast again a SE OTL, can pass square waves at 10KHz and is flat out to 200 KHz. That aint " No romantic floating..." But to each, their perception. Again, I really enjoy your Channel, thanks for setting me straight on that gigantic, is it, 170 Watt output, single ended, beast. Take care, and keep on educating Us.
@@BuzzardSalve There is no digital "word" processing in DSD either! It is a bit stream, not bytes. Analog: - relating to or using signals or information represented by a continuously variable physical quantity such as spatial position, voltage, etc. Digital: - (of signals or data) expressed as series of the digits 0 and 1, typically represented by values of a physical quantity such as voltage or magnetic polarization. Class D is a SWITCHING Mode. The devices are not operated in their LINEAR range, It is a DIGITAL SWITCH that turns on and off..."0 and 1".
@@glenncurry3041 The point in time at which the switching occurs is still determined by an analog process. Nothing else in the chain interprets those signals as binary. Also what happens during the transition period between switching devices also has an impact on the output post filtering. This would not happen in a digital system.
How freaking dense are you ? Do you know what archaic means? Christ I'm dealing with imbeciles. It means OLD AND ANTIQUATED and Class A is totally freaking OLD. Class A sounds great still after 100 years or whatever. . I even said that. Wow. Listen.... OK?
And what are speakers' performances actually??? Today we have even mid-level audio equipment with such a level of performance, that speakers cant support it. Yes, a class D amp will give you a signal with 0.0003% distortion, or - 120db but speakers are considered "phenomenally good" when reaching 1% ??? Not to mention subwoofers that are considered excellent with 5% distortion. On the 1W level, that is 85 - 95db SPL for drivers in a lab. And on 100db SPL there is no speaker driver that is better than 2-3% distortion. So, what a fuss about 110 SINAD or 95SINAD when we can't transduce that in real sound because of speakers. And no speaker manufacturer will show these data for their product unless some enthusiastic people with the CLIPEL system measure them. MAGICO measure their speakers, but they do not disclose what results from they are getting, just say some stories with common audiophile non-related descriptions. I know that water or something on the sun or vacuum tube, an amplifier can be "warm" but sound can't be a worm, or however is described. Amplifiers do not make sound, so how can have a "sound signature" You correctly clarify, that imperfections are turning into some sort of quality ??? by people with "experienced ears". Any school for experience in hearing education???.
Holy shit you sound like you are drinking the kool aid from those guys that live off measurement. Nothing means crap but how it sounds.... numbers are for engineers to design and many times the good numbers sound crappy ...
@@OCDHIFiGuy Perhaps because I'm an Engineer, a real one. I do not live of measurement, I just know what it means and how it sounds. And I'm an Audiophile too because I like Music and I know how natural sound is and HOw it looks when I measure it. The first rule of a real Engineer is not to trust anyone unless see, hear, or got the same results. One that just talks and walks can't ever do any of what talk about. and yes my power amp is high switching type, modified HYPEX module that I rearrange with SiC FETs and reclocked to 24.576 MHz switching frequency. And I also modify the switching power supply with SiC FETs, reclocked also, and add some more things so it can give a Supply voltage between +/-30 to +/- 150 volts and continuously 80A. So I leave it to you to find out what kind of amplifier I made actually.

I was intrigued and bought the book. I'm not an EE, my first undergrad in Math/CS. Read through it several Times and then took a gamble and bought His T-16 monoblocs. I've stopped building solid state because of His utilization of valves sans Output transformer, it just works for me. Grew up in a household with a baby grand, Steinway and played strings most of my life and nothing has come as close to the timbrel accuracy. My T-16 with 60 watts @16 Ohms with a power bandwidth from 5 Hz to 60 KHz, will power two of Ted Jordan's JX 150 NG's/channel in 12 foot long waveguides. The Minibeast I own has a power bandwidth from 10Hz-100KHz. Extremely analytical and FAST. His latest version of the Minibeast again a SE OTL, can pass square waves at 10KHz and is flat out to 200 KHz. That aint " No romantic floating..." But to each, their perception. Again, I really enjoy your Channel, thanks for setting me straight on that gigantic, is it, 170 Watt output, single ended, beast. Take care, and keep on educating Us.
Nad Purifi class d is my favorite ❤️
Class A still beats out everything. Dynamics on tap. More attack and decay in insterments.
Class A all day long .
This guy is dead wrong.
WOW
Class A Margarita 🍸
That's it !
Who else got up and touched the side of their amp just now to see hot hot it was.
I touched the side of my woman's booty to see how hot it was. 😋
WORD UP
Hey now!
I like my women like summer, NO Classsssss…oh wait!
It's summer all year long in Las Vegas !
Mikey you my long lost brurtha!! 😂
@@OCDHIFiGuy Remember, you are the Walrus!!!
I agree that as they are able to make Class D amps switch faster, they do get closer to analog.
But class-D is still analog. There is no digital word processing in all class-D amps that I know of.
@@BuzzardSalve There is no digital "word" processing in DSD either! It is a bit stream, not bytes.
Analog: - relating to or using signals or information represented by a continuously variable physical quantity such as spatial position, voltage, etc.
Digital: - (of signals or data) expressed as series of the digits 0 and 1, typically represented by values of a physical quantity such as voltage or magnetic polarization.
Class D is a SWITCHING Mode. The devices are not operated in their LINEAR range, It is a DIGITAL SWITCH that turns on and off..."0 and 1".
@@glenncurry3041 The point in time at which the switching occurs is still determined by an analog process. Nothing else in the chain interprets those signals as binary. Also what happens during the transition period between switching devices also has an impact on the output post filtering. This would not happen in a digital system.
So your basing the quality of the amplifier and sound by how efficient it performs ? Class A is Archaic ? Seriously ? wow Clueless
How freaking dense are you ? Do you know what archaic means? Christ I'm dealing with imbeciles. It means OLD AND ANTIQUATED and Class A is totally freaking OLD. Class A sounds great still after 100 years or whatever. . I even said that. Wow. Listen.... OK?
@@OCDHIFiGuy Doesn't it mean no X-over bias point, full wave no joining of wave halves?
@@johnpetrakis379 yep it does. Trying to keep out of that deep stuff for the channel
@@OCDHIFiGuy OK MIke!
Kevin, you sir are absolutely clueless
All due respect i don't agree with you... Please revisit.
You got to say more than that.... what part and why ?
And what are speakers' performances actually??? Today we have even mid-level audio equipment with such a level of performance, that speakers cant support it. Yes, a class D amp will give you a signal with 0.0003% distortion, or - 120db but speakers are considered "phenomenally good" when reaching 1% ??? Not to mention subwoofers that are considered excellent with 5% distortion. On the 1W level, that is 85 - 95db SPL for drivers in a lab. And on 100db SPL there is no speaker driver that is better than 2-3% distortion. So, what a fuss about 110 SINAD or 95SINAD when we can't transduce that in real sound because of speakers. And no speaker manufacturer will show these data for their product unless some enthusiastic people with the CLIPEL system measure them. MAGICO measure their speakers, but they do not disclose what results from they are getting, just say some stories with common audiophile non-related descriptions. I know that water or something on the sun or vacuum tube, an amplifier can be "warm" but sound can't be a worm, or however is described. Amplifiers do not make sound, so how can have a "sound signature" You correctly clarify, that imperfections are turning into some sort of quality ??? by people with "experienced ears". Any school for experience in hearing education???.
Holy shit you sound like you are drinking the kool aid from those guys that live off measurement. Nothing means crap but how it sounds.... numbers are for engineers to design and many times the good numbers sound crappy ...
@@OCDHIFiGuy Perhaps because I'm an Engineer, a real one. I do not live of measurement, I just know what it means and how it sounds. And I'm an Audiophile too because I like Music and I know how natural sound is and HOw it looks when I measure it. The first rule of a real Engineer is not to trust anyone unless see, hear, or got the same results. One that just talks and walks can't ever do any of what talk about. and yes my power amp is high switching type, modified HYPEX module that I rearrange with SiC FETs and reclocked to 24.576 MHz switching frequency. And I also modify the switching power supply with SiC FETs, reclocked also, and add some more things so it can give a Supply voltage between +/-30 to +/- 150 volts and continuously 80A. So I leave it to you to find out what kind of amplifier I made actually.
