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.

Any plans for a higher power mono amps in the future?

Yes.

3.  Amp designers would state their objective… straight wire with gain….low distortion with 2nd harmonic dominant….low distortion with 3rd harmonic dominant …etc….. I think Ralph has said this describes his amp  

A 'straight wire with gain' is better described by our tube amps since they don't double power as the load impedance is halved, which is in keeping with how a 'straight wire with gain' would behave :)

Our goal was as low distortion as possible. What distortion we get tends to the the 2nd and 3rd.

thanks ralph....I suspect that this is part of the explanation as to why your amps sound so good.

follow up question regarding a higher powered class d amp...would this be of much benefit to people running speakers with 90db+ sensitivity and listening below 85db?

It would be nice to be able to see photos of the interior of the monoblocks, as @ricevs has requested.

If only to make sure there is not a Purifi module in there. :)

Would be nice as well to see some data plots....

The Watt Wars of the late 70’s and 80’s is still live and well. People maybe shocked if they measured what they use at listening levels. So far in my room on 86-105 db speakers loudness, control, finesse hasn’t been an issue. For these amps. Not saying at times more power could be used. They can drive hard loads well. Nelson Pass talks about the First Watt. And builds amps to stay in Class A to various Watts then switch to Class AB. Why? He knows that almost all the time those amps will hardly leave if ever Class A. But people can say they have a 400 watt amp that mostly runs under 20 watts. Unless run really hard at High SPL with Lows dipping hard.  I’ve run the Atma-Sphere hard on Manepans at very high SPL with very complex music.  They showed no signs of fatigue or weakness. Next weekend I am going to try them in a larger room driving bigger harder speakers. My room is 30x25. 
 

    But hey if people feel the need for Watts…. Watts it is….  JMHO
