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 have an EVS 1200 amp here that Ric  built with all his well thought out modifications.  I prefer this amp over all the other amps I have had in my system over the last 7 years.  Bested my favorite Clayton Audio, Pure Class Amp,  which is no easy task! 
Nice job Ric! This amp is special and proof positive that Class D done right is going to be the standard very, very quickly. It just is. 
Yes, keep it on 24/7 for best sound.  No doubt.  As Ric says,  the caps will still last 15 years or so! No worries. The caps are cheap to replace folks. These amps are easy to work on when that time comes.  
It’s all about enjoying my music with my system sounding a good as it can.  Best Sonic foot forward. 
The EVS 1200 is simply a stunningly great sounding amplifier. Stunning! Ric, you are an audio wizard and a huge asset to the DIY and audio community in general.

Can't argue with a subjective opinion. It proves one thing only- you like it.

As for being an audio wizard and huge asset, you should save your praise for people like Bruno Putzkeys, who do more than wave their hands and ride on everyone else's coat tails.

Strange post? I could praise a near endless list of folks, but today I decided to pick Ric. Ok. Ric has taken the Ice boards and amp’s performance to the next level. 
Yes it proves this well experienced Aphile likes it. Not sure why you posted that second comment either? This forum is meant for users to post experiences.  Not meant as a launching site for wise guys.

I’m really having a hard time wrapping my head around why it is bad to improve the sound quality of a given piece of equipment by modifying it.

We’ve been doing it forever in this hobby (I’ll only go back 40 years ago to the Dynaco 70 as an example) & many have enjoyed the results.

Why the issue now?

Many moons ago when i owned my audio company with their blessing we would mod Bedini amps and sell them with our face plates. I did this with several TT’s, these mods allowed one European manufacture to enter the US market.

So mods have been happening for decades.
