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!

Can someone answer this for me please, especially George...
and people with class A amps live with class A defects

The only "defects" good class-A’s have is the heat they produce, this does not effect the sound, otherwise they are the closest to being the perfect topology so far.
Unless you live in central Australia, then the windows would have to be open and you’d hear this

Class A isn't perfect for all people nor all speakers.

Good Class-A IS the most prefect amplification so far.

Maybe on paper, George. However it's all about perception. It's all about how different people perceive sound differently. There is no universal best, regardless of schematic or measurement.

That’s your opinion vs technologies opinion.
The purest form of amplification if "done right" without any other flaws (except for heat) is Class-A, be it in opamps, tubes, or any solid state.
