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.

It’s ok to prefer no distortion… think acoustic guitar. 

Its ok to prefer some distortion… think electric guitar with tube amp and pedals.

Preferences are just those… no right or wrong  

Not worth disputing… not worth debating.

Thanks Ralph for making another great product.

I am starting to think class D is the bee’s knee’s man. Really enjoying the Rouge Pharaoh II and it is not even near broken in. Tube pre- Class D power section with the Hypex Ncore. Time will tell but I may be selling a couple of integrated amps I have in the tool shed.

Embrace the 2nd and 3rd harmonic distortion at low levels is the message. If you don’t like the message then move on.

Certainly - the message seems to be that the 2nd and 3rd harmonics are better than the hash of 4th + .

I would like to see an example PSD of a 1kHz tone, and the harmonics.

Someday would love to try a set of these! But got to say, pretty solidly in love with my current GoldNote PA-10 (class A into GaN power stage). But truth and proof in class D from here on out.

@riccitone the Goldnote PA-10 is simply A-D not GaN I had them at one point. 
not sure what Core they are using. I might be wrong.

The PA-10 is a 200x80x260mm (WHD) Class A/D hybrid power amplifier. In stereo mode, it’s specified at 75wpc into 8Ω (150wpc into 4Ω, 300wpc into 2Ω). Enough for average-to-high sensitivity loudspeakers.
