Class D

Having owned a EVS1200 for over a year now, and having made a few component and cable upgrades, most notable to date, I replaced my Emerald Physics KCIIs (with Wire World OCC wire and Clarity cap upgrades as new) with EP 3.4s (also with Wire World OCC wire and Clarity cap upgrades) which I played without adding 2 SVS powered subs until about a month ago. I feel sorry for those who didn't jump on this amp, as he has stopped making them.


Both Absolute Sound and Stereophile have glowingly reviewed the PS Audio M1200s (same IcePower modules, but stock). I am confident that the EVS 1200 would stand out against them for barely 1/3 the money

I don't know, you would have to have some serious vision problems or some serious dogma problems to this this is an unrecognizable square wave .....

George telling other people "they don't understand". That is ironic.

Really! Wake up and smell the roses!!! and stop your shilling!

For one it was done at very low power, would be much worse at normal power
Yet even at very low power anyone can see it’s distortion rising markedly from 1khz! up, and then much sharper after 2 to 3khz!!! to a cliff face at 5khz and up!! https://ibb.co/6rfG2ts

Here is the distortion from a good linear amp. https://ibb.co/8rTdp3D

There you go georgehifi, illustrating that YOU do not understand how electronics work and how Class-D amplifiers work. Signal level will have 0 effect on this. There is something that will though.

And here is the distortion of a very good amplifier:

Makes your "good linear amp" look like a 1970’s discount Realistic Receiver.

And if you can't see that that 10KHz square wave is a quite good square wave, then you are even less "aware" of audio/signals than I thought.
