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.

George, those Class D Audio USA amps look
nice, but boy are they butt ugly.


Take a look at their dac/ streamer that’s coming out. It even supports RUNE.

Look at the Legacy Audio iV4 amp review on Dagogo

That reviewer really liked the Technics amp especially its phono sound and capabilities including ability to digitally correct per cartridge at least with the Ortofon black cart used.

Yes, I thought that was a neat feature, the way the Technics "listens' to the cartridge and applies its magic to it.
I found another reviewer who's somewhat of a Technics fan and his take on the R1000 and how it compares to a much more expensive Technics line: https://www.youtube.com/watch?v=YePQyDV52Zk
He, too, is a big fan of what the Technics does for LPs. I believe it can store up to three different settings for as many cartridges.

All the best,
