Atma-Sphere Class D… Amazing

Well I can say Peachtree when in a quality system you’ll hear the pitfalls of them.  The more revealing system the more pitfalls you’ll see. They are a dry,  lifeless Amp. Lacks in details and is very fatiguing. They won’t even be close to Atma-Sphere Class D. Maybe 40% of the Atma-Sphere at best. Guessing there is some degree of Atma-Sphere haters here. Comparing the Peachtree to the Arma-Sphere is like comparing a Ford Pinto to a Mercedes 380SL. JMHO…. 
 

So in the reviews today and tonight. The Tube guys liked the MA-1’s better. The  Pass guys like the MA-1’s better for the Blume, Soundstage and space. But liked the Class D’s over all. As I suspected would happen. My MA-1 tubes are very laid back. If I put different tubes in there maybe a different response. The Pass guys have the XA30.8, XA60.8, XA250.8  x250.5. All very impressed.  Will be putting the class D’s into their systems next for an comparison. A lot of comments like these are only how much?  One comment “maybe the best amp they’ve heard under $10,000”. All agreed at $5400 they are a steal for the sonic qualities. And all agreed there is a degree of give and take between the MA-1’s and the Class D. Like I said next is to put them into others systems and see how they do in various systems. All are world class audio systems. 

pstores,

Have you heard (in your system) the new Peachtree GaN 400 or are you referring to an older Peachtree amp?

hgeifman-  I've had the new Atma-sphere class D monos in my system for exactly 3 weeks today not using a pre-amp and they sound fantastic.  I researched whether or not they could be driven by my Cary DMS-600 before I took the plunge.  They are replacing my tube amp.  I've not used a pre-amp in 11 years so couldn't tell you whether a pre-amp would improve.  The tube amp I ran was a Music Reference RM10 MkII which was ideal for running direct or with a passive pre.  The monos sounded good out of the box but after 3 days came alive.  I'd really like to try an Atma MP-3 with them but it would be a rather expensive experiment.  I was told by Cary that the DMS-600 is truly balanced so I'm not sure I would gain anything.  My system is posted here.  Contentiousness abounds, LOL!  Now back to listening to music cheers.

Sounds like someone is having fun with semantics at this thread's expense.

Quite the contrary.

From the distortion spectra, research has shown that certain distortion profiles will produce certain "sound"- compare the distortion spectra of many tube amps vs ss a/b vs class d and you find many describe the tube sound as "warm", "rich", "lush", etc. Class d as "neutral", "clear", etc. Certain harmonic profiles lead to similar perceptions, thus, from the measured performance, we can indeed make certain predictions on how an amp will "sound". Will everyone "like" that sound? No. This isn't semantics, it's psychoacoustics, an admittedly soft science.

+1 on your comment about which Peachtree amp

My own extensive experience with my Voyager GaN 350 (said to be the same as the Peachtree) is that is chameleon-like: a change of vibration control devices (the OEMS suck the life out of the leading edge, overall softening the sound), changing power cords or interconnects, or anything in the chain is readily heard. Another huge factor is whether the music is being played at the PROPER volume
