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!

I am waiting on a Class D amp that will sound as good as my AHB2 monos but have much more power (2 Ohm). I was hoping that Purifi would release a second generation amp module but looking at their web site it seems they have moved onto driver design.

I have a D-Sonic M3a 800s Class D amp (Pascal module) + CODA 07x preamp on the floor standers that the AHB2 previously drove. It is a better power match but I still think the AHB2 is the best amp I ever heard. The AHB2 is the quietest and cleanest amp I have ever heard.

My AHB2 monos are now doing headphone duty with the CODA 07x preamp. A perfect combo for my RAAL SR1a headphones.

@mapman What are the best Class D in your opinion? I have a Pascal based D-Sonic M3a 800s that I use for bright headphones (it likes power). It works great but I am interested to know about others.
