Atma-Sphere Class D… Amazing

Today I picked up my Atma-Sphere Class D Amps. These aren’t broken in yet. And they are simply amazing. I’ve listen to a lot of High End Class D. Some that cost many times what Atma-Sphere Class D costs. I wasn’t a fan of any of them. But these amps are amazing. I really expected to hate them. So my expectations were low. The Details are of what I’ve never heard from any other amps. They are extremely neutral. To say the realism is is extremely good is a gross understatement. They are so transparent it’s scary. These amps just grab you and suck you into the music. After I live with them some and get them broken in. And do some comparisons to some other high end Amps Solid State, Tubes and Class D’s, also in other systems I’ll do a more comprehensive review. But for now, these are simply amazing amps.. Congrats to Ralph and his team. You guys nailed on these.

I’m certain Ralph just slapped his forehead that his five decade journey in audio design is now complete. Congratulations Ralph!

I believe that @ricevs means well with his suggested modifications, but it's easy to be an armchair quarterback and critique the hard efforts of others. Ric have you given thought to bringing an amplifier to market loaded with all of your ideas to compete in this sector?

I too am a class D convert after many years and many amps.  It is really hard to say if they are better than class A A/B because of everything has changed along the way, speakers, preamps, DAC’s cables etc.  I still love tubes and will probably always have a tube pre with a tube regulated power supply, a professional (recordings studio DAC / Streamer) and class D Amps because of sound, weight and heat.  In summary class D with ultra fast switching (GaN) is pretty good.  Good enough to pay attention too.   I own AGD and don’t plan to change any time soon. They just work and sound great and should not be ignored when looking at amps.

A couple years ago Ric came out with his EVS 1200, based on the same IcePower modules that PS Audio eventually came out with using the same modules in their M1200s 9but at ~ 3Xs the price). Ric made a lot of improvements to the modules, though some issues could not be addressed. I raved about it in a AG thread that had many hundreds of followers, that is until my LSA Voyager 350 GaN amp arrived (about a year later). IMHO, from the first note, there was simply no comparison. Ric mods stock Voyagers, which may be the best audio bang for the buck going

How about changing the op amp on the input to a discrete one? Discrete op amps are generally more real and open sounding.

Too bad there is no puke emoji here...

How about you market your own snake oil amp and leave the science and engineering to the professionals?
