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!

George, those Class D Audio USA amps look nice, but boy are they butt ugly. 
Btw,  Class G and Class H are really nice sounding.  Typically they are the first X # of watts in Class A and then switching comes in above that.  I've heard a few and owned one (Creek Evolution 100) and they sound really nice.  
I think Class D can be very good but class AAB done right is more natural  overall.My Coda CSIB integrated amp Beats many excellent separates, in class D not one  great Integrated , Merrill Audio  very good but at $20-  $30 k No thanks too many Class A-AB amps That  are better .I have have heard others ,  which are very respectable ,but still a couple steps behind from my experiences.

 Yes not the best looking, but what’s inside is what counts, they "could" be as good as $5k ones for just $699

Otherwise if all that’s important is the look, then I call those "Glitz Queens" and they are usually the ones that parade their glitzy stuff on glitzy racks in between the speakers.
Not caring they are totally stuffing up the imagine properties by doing that.

But they don’t care as they are hypnotized by the shimmer of their equipment they are gazing at while trying to listen..
