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!

ralph good luck in your work to launch the amps

in the event you want some consumer testing/trial, i'd be happy to help

i don’t have torture-chamber speakers to drive (mostly british monitor types - harbeths, proacs bigger and smaller, spendor, also spatial m3s, vandy 3a sigs, fritz monitors and of course old stand by esl63’s), then have quite a few traditional ss and tube amps to compare, ranging from several arc, lta zotl40, air tight, carver 275, pass/fw, hegel, devialet and w4s class d...

It strikes me that the one other contender not yet mentioned in this thread is the LKV Veros PWR+.

It's been very well reviewed, but I don't know how many units are out there in the field.

I have only seen the blah Herb Reichert review of the LKV (says it beats an old class D amp and is somewhat competitive with a $3500 Rogue tube amp).  Are there other reviews?

For $10K I would expect more.

I have been living in the world of class D for many years.  Had a TacT/Langdorf Millenium for 12 years, then went to a NAD M-22 for 2 years.  Now I have moved to PS Audio M-1200s.  With every change it just keeps getting better and better.

I think the actual chip used has a lot to do with it too.  As time goes on, hobbyists are finding out which chips are preferred over other ones.  Like the 3116, 3118, 7297 as opposed to the earlier 3886.

Check out the Fleawatts by Derek Sanderson.  They sound amazing at a much lower cost than many others
