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.

How does the output of a class D-amp (AS) varies with speaker impedance?

100W  with 8Ω....and then? 200 with 4Ω?

And what about really difficult speakers that can go down to about 2Ω?

Is there any limit to when the speaker load affects the performance?

@fredag 100W with 8Ω, 200 with 4Ω. Current limit protection will kick in with lower impedance loads- as long as not to full power the amp will double its output power, but will reach its protection limit at about 250 Watts.

@atmasphere Thanks! How about balanced operation. I understand the amp is not balanced/differential....can it be made with class D? (not ONLY balanced imput)

@fredag They have a balanced differential input (and RCA inputs are provided too). I run them balanced at home.

@atmasphere Great! I use only balanced cables at home. The other part of the question....can they be made differential from INPUT to OUTPUT, as many conventional SSs are (ML, Pass,Moon, etc)? Is there a point?
