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!

@mglik  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.

Pricing for this stuff is all over the map. So, what else is new? 10, 20, 30k for "all that and (literally) a box of chips?" "Oh, but you are obviously a neanderthal and not capable of comprehending what goes into development."

OK. So a $5k class D amp in this New World will be a "compromise"?

Sorry, I have a pair of Magnepan 3.7i running with a Marantz amp. It just makes we want to listen to music. I paid $2,500 for the amp. Obviously, I have the dumb and an unrefined aural palate.

I haven’t been listening for 5 decades... just 2; however, I do know that $38k for an amplifier is STOOPID. I guess half that is a deal, and ignorance is Bliss.

A very good friend of mine has the mid sized Magnapans. He tried the pair of M500 MkII Monoblocks and said that they had plenty of power and sound great. However he pulled them, installed two Shiit Vidars ran mono to replace the dragons. He told me the Vidars were not as powerful, with less dynamic slam, but had more detail, the highs on the Vidar were much smoother, velvet on voices. Electric guitar did not bite like the Dragons. The Vidars on the lows were deeper, clear. He has the Freya as the preamp. He did try a crown 2502 and said it rocked the place. Huge power and control. It grabbed the
Maggied and they said, yes sir!  He said the dragons over all sounded a bit  better, more detail.
