Switched to Class D or get left behind?

[Mr Peabody]

Maybe some of the ancient class D amps created enough HF drama to sound tubish (the low/no NFB designs lest Ralph slap me) , but those days should be gone

Glad to see you agree with me on something Interesting you stoop to subjectivity.

Not surprising you don't know what that means.

I know what Frito Lay "chips" are

Even more surprising why bring your speakers anywhere since you don't know what it means to listen?

Anyone sensible might realize I "bring my speakers anywhere"...for others to listen.
Unlike yourself, I do know what "listen" means. I do understand why you wouldn't want them in your room vs your JBL/MLs in front of peers ;-). Friend has a pair of those, quite familiar with them.

Cool. I know what subjective means, unlike the must know objective metrics amp class, PS parts "quality", price tag, etc, etc, etc pseudo subjectivists. Phew

I am also certain if a person has a much larger room, or likes to listen to concert levels in their home than the WPC discussion would be more important.

Just did an install with an all Mc system in a very large room. MC312 and MC303. Yes it gets loud ;-).
Maybe you could have Ralph do a custom version with blue lights...

I don't think most people know how to actually listen and what to listen for. I was lucky enough to have been show how otherwise I wouldn't either.

Many simply listen for overall tone and don't understand that is a tiny fraction of critical listening.

So I think for those people - who really listen for tone only - it may sound similar in as much as some class D can be decent if you are listening only for the overall tone.

As an example I have a TEAC class D amp here. It is the best Class D I have heard at any price. It still doesn't come close to tubes. But if you only listen for overall tone it does sound similar to some tubes.

Think of those people as 1 dimensional listeners rather than 3 dimensional listeners.

There are hybrid integrated amplifiers with Class D and Class A tube pre section that sound very nice... I own one and enjoy it immensely.

Be nice Peebody.

I do similar but separated tube pre https://pt.audio/2019/03/17/florida-2019-soundfield-audio-vac-nad-big-sound-or-little-you-decide/

That is definitely the way I would do it if I were to.

He thinks from his experience, class A and AB have more grunt. Class D is clean and more tube like.

If the power supply for the class D is a bit wimpy (which is fairly common, since some people don't realize that the supply for a class D amp has to be very robust), I can easily see this being the case. It does not mean it extends to all class D amps, just that one...

I guess I am surprised that a company like his does not sell direct or at the very least publish the suggested pricing.

We do sell direct if a dealer isn't close by. The pricing is kept off line since people overseas will see a different price locally due to import duty, luxury taxes, shipping, etc., by request of our overseas distribution.

Ralph, why are Mola amps $50k? As in, is there anything above a d beyond what you have done to merit the cost. Or is it a name they base the $$$$ on. Selling to audiophile with big wallet with a big $$$$.

You'd have to ask them. It may be they are pricing to what the market will bear rather than to a markup formula (which is what we do). The former pricing scheme results in what is known as 'Veblen Goods'.

 

[Kingrex]

Yes. How would you know what I do??
I don't make amps, but I have, on several occasions, done exactly that. On even more occasions, I bring my speakers, which I do make, with Class D amps, to demo the variable directivity and cardioid to 40hz capabilities that near zero audiophile system can have. Lots of smiles there ;-).

Those are false dichotomies of your minds creation. Why does the Class D have to be "affordable" vs $$$A/AB?? Who made that imaginary law or rule?? AGD, Mola are in the $50k range, your system list doesn't suggest that as merely "affordable". You missed the Caltech wine data again, or didn't understand the results?


Correct, because as you just proved unambiguously, objective metrics like amp class and price are absolutely what dictate the "It's all subjective" crowd decisions...those completely oblivious to basic word meanings

Yeah, that's always been a criteria for controlled listening test rejectionists . "Trust your ears, just listen"...hmmm wonder what that means.

You have brought a class D amp to a home with say a Gryphon Apex or Dartzeel 468 and played them head to head? What amp did you bring and what did you hear?
