Switched to Class D or get left behind?

I know what Frito Lay "chips" are :D

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.

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.

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'.

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 :D

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?

I have a friend with both Gryphon Apex and Dartzeel 468. His speakers have 2 woofers, 2 midrange and a single tweeter, plus a 500 watt class H plate amps to drive a sub he made. I think 12 inch, maybe 15 inch driver. Anyway 100 of us were there and we compared it to Primare class D amp and the Primare completed destroyed the other amps. 100 of 100 people agreed. No listening controls were used whatsoever so you can take this as fact.
Btw, whaddya think of the AVS thread with ML that I linked?

It seems to me that Class D enjoys a poorer reputation than it deserves largely because there are many "amateur" builders who cobble together "Purifi Eigentakt" or other amps that should be exceptionally good, by buying in Eval(uation) boards and ecconomise of such things as power supplies. The best Purifi amps are built by the big brands and are considerably more costly (and rightly so) than these cheap garage-built offerings sold direct or through Ebay.

Not all "Purifi Eigentakt" amps are the same - far from it - and there are other exceptional Class D amps such as yours that are designed by people with the skills to create amps that will rival or better other classes or tube amps at 2 or 3 times the price.

Yes. I'm sure that's one of the reasons you read such variable comments about Hypex and Purifi.

You mean judge amplifiers individually rather than indicative of an entire class?? What's wrong with you? 😊

100 people? Really. Do you mean 10? 100 is a whole lot of people to entertain at your home. And I would think some people would have posted about what they heard.
Curious, did the owner buy the Primare? Or did pride make him/her keep what they had?

You are making me more a believer. I told the guy who made his own speakers I showed what you said. He said he doesn't think about amps anymore. He's done. He said it was Jason, the Audiophile Junkie that lead him to the amp. Jason is using them on his Popori speakers. That's a good speaker.
