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!

George,
So much drama over nothing. Its just words. Here is how I describe it on my website:

No it’s lies being told to members for the sake of "trying" to gain notoriety.

End of story, if the power supply (SMP or Linear) is not switch on and no electrolytic caps are being charged up (as you said), the neither is the amplifier!!!
SO THE AMP CANNOT STAY WARMED UP no matter even if you leave it in this state 24/7 like the other one says.

You guys are just digging yourselves a massive technical bottomless pit.

George,
When the mute switches are engaged the amp is not being warmed up.  When they are not engaged then the amp is on and it is being warmed up.  What do you not understand about this?  If someone wants to warm up the amp and normally has the mute switches engaged then they just unmute them and wait till it is warmed up and start listening......just the same as anyone with a class A/B amp that does the same using their power switch.  What is there to argue about?  Do you argue with yourself when you are alone?  What lies are being told?  What notoriety?.....the only notoriety here is what you create......and you have created quite a notoriety.  Why don't you try a loving notoriety?  That would be sweet.

You guys really need to remember what ** are in your post

I said
To those who want to understand, why it’s better to turn off your amps, here it is simply as possible.
(as they like to be drained and recharged otherwise a false permanent "empty floor" happens and your electrolytic power supply caps won’t have the uF storage ability they once had when new

Nonoise asked
My EVS 1200 has dual muting switches. Will muting them be as effective?

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 24/7 eric thinks!!!!!!!!!
