Class D amps that are superior to all or most?


Recently, I have heard about some Class D amps that may be close to the best there is regardless of class. Certainly, this technology has been in development for decades. The main issue has always been the switching power supply. In this regard, I have taken notice of AGD. They have created a whole new power supply that “switches” at a frequency 100 times the normal silicon based MOSFET. The designer uses a gallium nitride based PS. Interesting, it is enclosed in the KT88 glass envelope that sits on top of his amps. I am aware of two more pricey amps that seem to be also at the top- the Solution and the Merrill. There must be others that compete for the title. After my thread, “Is there a SS amp that can satisfy a SET guy?”, I am still on the quest.
Don’t want to spend $50K!

@coltrane1 I've explained earlier on this thread why class D has opportunity to do better than class A- and that has to do with how feedback is applied. My comments on this are near the bottom of the first page of this thread. Keep in mind my company has been making class A amplifiers for the last 46 years.
AGD are the ONLY amps in 50 years in that grab me in such a way that is near impossible to not listen. Now listening, it is very difficult to write these few words.

The AGD Audions did and continue to do the same for me.
