Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other???

Eric, I’d love to pull all the lore out of my pocket and then, as I give to to all, it turns into money in their pockets (for builders and buyers), and better hifi for all as a final outcomes.

As that is how this works, the reality we are dealing with ..when it comes to talking on forums.

Since I worked hard, very hard, over decades, pretty well 7 days a week...in order to know this stuff inside out.... I’m reasonably reluctant to just give that away.

I need to be able to put food on the table in order to have the hard work be of use to me personally.

So, I’ll do the thing where I will make the self aware and willing to work at it, make them aware of the problem’s realities, aware of the fallacies of their argument..and then they can work it out for themselves. Which is all an intelligent thinking person actually needs--if not knowing where the mistake was made, but just to know the mistake exists, at all. That's more than enough.

If I was purely business minded and had zero empathy for my fellow man, I’d keep my damned mouth shut and let ignorance flounder, for as long as humanly possible.

Some of us say as much as we can in that spirit, but we still get beaten up by the remorselessly ignorant, no matter what good we try to do.

" The human ear is capable of decoding intermixed harmonics and timing cues into the 200khz plus ---with zero jitter. Micro and macro signals intermixed. With two ears doing this as a combined spaced pair, with the micro and macro intermixed temporal cues."

Hello teo,
     
     Are you certain this is true?  I've never heard or read this claim before and I'm very interested in reading about any research you know of on this subject. 
     Contrary to your apparent opinion, I am very interested in the subject of human hearing and how the brain processes the signals from our ears and determines how we perceive these inputted signals. 
      I believe the understanding of the ear-brain relationship, along with the understanding of room acoustics, are critically important in explaining how a solid, stable and 3-dimensional sound-stage illusion is able to be created in a room utilizing just 2 properly position speakers.
     My understanding is that humans cannot detect frequencies above approximately 20,000 Hz, which I believe is mainly based on early 20th century empirical research. In fact,  audio recording and playback equipment since this time has been designed and built based on this upper frequency limit.
     Before I go any further, however, I'll wait for your reply just in case I'm misunderstanding  something in your statement: " The human ear is capable of decoding intermixed harmonics and timing cues into the 200khz plus ---with zero jitter."

Thanx,
  Tim

You just don’t want people to like Class D.

Really!!!!
I’m pushing Class-D with this newer technology, because the old technology that’s basically been the same since it started (save for some input detours) is flawed. Reason why all detractors ALWAYS find the mid/highs are not right.

You are the one every time I bring it up that is putting **** on this new GaN technology, possibly maybe hoping it won’t advance every time I’ve talked about it, what is it, do you have monitory interest in present day Class-D, because you sure do push the old, never the new.
I want it to advance so the mids and highs get the same respect the bass has, then I’ll get 2 pairs to take the place of my inefficient boat anchors.

We now have GaN users Merrill, Technics and  AGD Production.
And as GaN in an email said

" We are unable to reveal due to the Non-Disclosure Agreement (NDA) with our customers.
But I can assure you that there are several customers globally, developing with eGaN FETs for Audio applications, primarily due to the benefits it offers."

This guy knew what was coming a couple of years ago, even though not one amp was yet built using EPC's GaN technology.

The class D AGD Vivace Monoblock amps are a steal at $15k USD per set. I have heard they are the real deal in rendering an authentic 3D soundstage of the correct timbre pace and dynamics.
