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.  
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 agree with most of your comments as I also mod, upgrade and build gear and cables.  Passion of mine.  Just look at my virtual system. 
However, one really cannot make a blanket statement about how all gear does not sound any better being left on.  Some do and that has been proved out over time with my ears and a resolving system.  Most gear needs under an hour, but some dacs and amps can take up to 24 hours.  This has been true of my Lyngdorf 2170, TRL SS amplifier and several dacs.  
My EVS 1200 amp is staying on!
