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

     teo_audio stated:

" 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,

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.

they are the real deal in rendering an authentic 3D soundstage of the correct timbre pace and dynamics.

I believe it, it has the GaN technology.
Probably could have been below $10k if he didn’t use that marketing "tube thing", may have been even better sounding without tube pins in the signal path. Bet there’s a cheaper MkII without the tube thing soon.

Even he said

"Company founder Alberto Guerra admitted that he did it largely for the sake of visual aesthetics. “Otherwise a class-D amp just looks like a box,” he said. The amp uses gallium nitride MOSFET output transistors, which Guerra says switch faster and allow the amp to have a noise floor in the -120 to -130dB range. Power is rated at 200W into 4 ohms."
