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

     The EPC eGaN FETs switch 10x faster than silicon MOSFETs and have zero stored charge.  I'm guessing that probably improves sound quality when used in a class D amp.
.
  Elegant Audio Solutions in Austin, Texas, created a class D amplifier (200 w at 8 ohms and 400 w at 4 ohms) using the EPC eGaN FETs with THD+N as low as 0.0005% and very low feedback. Moreover, this is done without the need for a heat sink and eGaN-based amplifier can plug directly into the standard amplifier implementation of many existing systems. I'm very interested in auditioning this amp in my system. 
Here's a link to the amp photo:

     Anyone want to volunteer to make me a pair of mono blocks using a couple of these amps placed in nice aluminum chassis with XLR inputs, IEC jack and rocker ON/OFF switch on the back and a single blue power status LED on the front?

Thanx,

Here is the PDF to the  eGaNAMP2016  GaN amp.
Steve Colino said if one wants even better sound from it, you can add a heatsink to those GaN fets and take the switching frequency up to 1.536mhz.

Hello georgehifi,

     Thanks for the link to the EAS™ eGaNAMP2016 amp module.
I’m a bit confused, is this an EPC or EAS class D amp module? Or is EAS just using a standard EPC module for their amp?

     I was assuming that EAS built a proprietary module using EPC eGaN FETs using either an EPC or Peregrine driver but I'm not certain.
     I was also assuming EAS intended to sell their modules to OEM amp manufacturers and not to individuals for diy amps since no prices are listed.
..
I noticed the EAS™ eGaNAMP2016 amp module is amazingly small (4 x 2 inches) and efficient (96%). The switching frequency is still sub 500KHz but, as you stated, this can be raised substantially with the use of heat sinks. Class D sound matching or surpassing the sound of class A?

Please buy 4 of these modules from EAS and put them in nice chassis with XLR inputs, heat sinks and at least 1.6 MHz switching frequencies. I’ll buy a pair and you keep the other 2 and we’ll report back here on the performance results.

Thanks,
Tim

Just get the GaN Development board or eGaNAMP 2.1 Evaluation Kit Stereo Evaluation board already made up, with everything inputs outputs, give it +/- 32v power and put it in a box. I believe Digikey has them, and many others.

Okay, thanks.
