new GAN amplifier

I once made the class D > DSD analogy on another forum and was met with enormous hostility from the Class D faithful.  

The believers provide the missing bias.

Anyone that thinks GaN is all the same,  send me Wallys $2K attempt at lowballing the market  and "stealing " all the sales as the lemmings think anything GaN is the same.. Il compare it to the best Ive heard AGD, and if Wallys is undetectable I'll be honest and admit it , then give the news to AGD and tell them to get thier ass to work along with sending it back with $100 and a thank you for letting me compare. I am guessing the AGD will embarass the crap out of Wally and his huge claims of greatness just due to using a certain material.  It will help to prove the point that curcuit design anmd layout  trumps everything. Maybe Ill put a Silicon based Class D against .... maybe I'll put an Ice power silicon Class D made by one of my favorite circuit designers against Wallys GaN amp... my purpose is to show that design is far more important than material. I simply dont think Wally has any Genius designers making his $2K amp.. Lets prove it shall we ?   

GaN FETs suitable for a Class-D output stage and superior to silicon devices are relatively inexpensive now. Even in a $2,500 unit, they use of GaN shouldn't command that much of a premium.

Thorsten Loesch particularly shows his lack of knowledge.

Agreed - its obvious he conflates 'clock rate' with 'symbol rate'. Its not the clock rate of the classD amp which is around 500kHz, rather the symbol rate. There's no clock rate in fact - because classD is an analog amplifier, not a digital one. Since there's no quantization of the symbol widths his comparison to DSD or S-D DACs is totally meaningless.
