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!

So, does muting my EVS1200 have a benefit, and if so how often and for how long?

Stop calling it a mute, (as by ricevs, IF correct?) the amp is OFF!, and yes all the electro caps are drained and everything is de-powered and charged up from empty when you turn it on again. (good for the caps)

And it is NOT on and in a warmed up state 24/7 as some😵 here think!!!

A mute only stops the input signal and leaves the amp switched on!
It may possibly have a input sens circuit (standby) which can turn the amp all on when a music signal is detected at the input like a subwoofer standby.

Thanks Ric. I am supposed to be getting the long awaited Voyager soon, but until I actually hear it I cannot say whether I will also keep my beloved EVS1200. Keep in mind my room volume is HUGE, and so far I have needed big power to properly energize this room
Also I am 73, so even though I expect to live well beyond my mid eighties, will my ears be as discerning then as they are now?

You can see the insides of the Voyager on Underwood's site.  You will want it modified.  Lots to do there.

Yeah, the designer couldn't have known how to make it sound as good as a snake oil salesman.

HIssssssssssssssssss went the snake............and glooooooooooooop goes the oil.

Thanks for the Love.....you and George must be buddies.....he he.

The fact is that everything makes a sonic difference and no one knows everything......so there are no perfect components.  This is why all class A/B amps sound different from one another and same with class D.  Every single thing you do makes the sound different.  This means that many many people can improve on any one design.  Not just snake oilers...but even flat earthers.
