Atma-Sphere Class D… Amazing

I haven't heard the Atma MA1's but do have 97db speakers and the Atma M-60's are better than my 300b amp in my system. I used the Allnic 300b amp for years before getting the Atma-sphere. The 300b is great, but not as good in my system.

I also have had Bel Canto Ref 1000, and Merril Audio Veritas in my system, Although the Bel Canto was with Joseph Audio speakers. I am not a huge class D fan, although if you change your system to them, you can make it work well.

What convinced me to try them was Ralph saying he uses them in his system. That caught my attention. Then when discussing with Duke Lejeune, he said he was planning on getting them for his system, although he said the bass would be different from the M-60's, not necessarily better, and making the statement that the M-60's were a hard act to follow. That did it.

@pstores, You're fine.  Nice post on a very interesting piece of gear.

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.

I can’t wait for your precise and articulate tribute.

In full knowledge that you may only change one variable between comparisons, all other things being held constant.  This will invariably involve comparing components that are not technically equivalent.

But you know that, having read all of knowledge provided on Ralph's website.

No, not really.  I seek informed analysis from one who is cool, calm and collected and in control of their cognitive facilitates.

Idle current is so low that it invites leaving them on 24/7 yet if the amps happen to be cold, they need little to no warm-up to sing.

@pstores, congratulations on your purchase!

I've had my pair for ~ 2.5 months now, and leave them on 24/7; it is amazing how cool they run (like barely warm at all, unlike my other amp which is a Class A Pass). I might have 300 hrs of play time on them at most and think they likely have improved some over that time.

I'm feeding them with a Meitner MA3 and Sim 740P, and they are most certainly not out of place. 

Atma's are good but overpriced....400 watt Peachtree is 90% there and costs under $3,000....I'm hearing details I never heard with my tube and class AB amps that I love. Every piece of music I play sounds "new" with all this added detail...very exciting....but I still love my 845 SET Tubes.
