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!

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

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 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.


Once again, https://www.youtube.com/watch?v=B8W_zAD5Mcw yeah baby!

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

The capacitors will last longer if they are turned off most of the time. This is the same for any amp, no matter what the class. However, do you really care that the caps might need replacement (both amplifier boards in your case) in 10-15 years? Do you really think you will keep your amp that long? ha ha ha. All amps will become boat anchors....some sooner, some later. Does the amp sound better after it has been on for some time? Listen and find out. Some say class D needs to be on for two days to reach its sonic potential. Some say it does not sound different if warmed up. It does not matter what George says......he will always say the same thing.....even without listening. It does not matter what anyone says.....believe only your own ears. Find out for yourself. Don’t be lazy.

Two factors that stress capacitors are large current draws and high temperature. In a class D amp the current draw in minimum (the opposite of class A) and so is the temperature. Class D amps are super efficient and cool running. Still, it is a good idea to replace all the main electrolytic caps in any amp every 10-15 years.

Look at all the new amps coming out now......some will be modifiable....do you think your amps will be with you through next year? I doubt it. We have the Atmasphere amp, the Mytek amp, The Wryed for Sound amp, the new higher powered Orchard, the Premium Audio and the LSA amp all with GaN output devices....all either released or about to be. I am sure there are more on the way. A higher power Purifi module is about to hit the streets as well.

I just now noticed a pic of the insides of the new LSA Voyager amp......"lots of stuff to mod there"......he says, wringing his hands....he he.

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.
