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!

My EVS 1200 has dual muting switches. Will muting them be as effective?
No, I didn't. 
I just alluded to the fact that you love to argue.

All the best,

Amplifier class - whether A, A-B, D, or T is irreverent if the implementation is bad. If all else is equal, class A is the way to go. No compromises and a short signal path are key to achieving optimal performance.

You could have a class D outperform a class A. However, it would be unlikely for a class T to reach some pinnacle level of performance.

Sorry, wrong Curly, it was tweak1, same same.

I said
"Muting"
If your referring to keeping electro caps in great condition just by muting, NO!
Only being switched off from the ac mains will do, either by the amps "AC power switch" or the ac wall socket.

You (ricevs said) your words!!!!!!!!!
George is wrong, in this case. The muting circuit in the EVS1200 amp both shorts the inputs to ground and puts the amp in standby (turns off the main power supply.....SO NO CAPS ARE BEING CHARGED!!).


Like I said the amp is off not muted.
No caps being charged, means no amp is on to be warmed up!!!!!
So leaving the amp in this condition does nothing for it being warmed up for it to sound better either as eric thinks!

And like I said your not doing all electrolytic caps any favor’s by leaving amps on anyway, your making them have less storage capacity as they get lower uF, instead of being re-generated (polarized) when turn off and fully drained then charged back up again when turned back on.
In other words they get a false empty floor memory, like some batteries. And not to mention your cooking them and drying out the electrolyte as ieales tried to tell you.
