Zero Feedback: Atmasphere vs. BAT

Do Atmasphere and BAT have similar sound because they both use low or zero feedback tube designs?

I am considering these amps for my 8 ohm 89db Spendor S8e's.

I am looking for smoothness, Transparency and sound on the warm side. I am leaning toward a BAT VK75, it can be upgraded and it runs AB instead of the hot class A. You can also upgrade to VK 150. From what I can gather the 140 watt MA1 is superior in the area of dynamics, that would be the main reason to go Atmasphere to the best of my knowledge as OTL is super fast and more of a rock out style.

I am looking for used gear that can be supported over the long term by a good company.

For "smoothness and transparency and warmth" it sounds like you are looking for a Cary, CJ or other el34 based amp; or perhaps a 300b amp.

Atma, IMHO runs pretty neutral. BAT runs very lean - a bit like Audio Research. So, no, BAT and Atma do not sound similar. IMHO, the Atma and Audiokinesis combo will be very, very musical and better many systems costing much more. The big Atma will heat up a room, but with a properly matched speaker, you will be fine with the m30 or m60.

It has been about 4 years since I have heard the BAT gear and perhaps it was poor synergy, but it sounded lean and a bit veiled to me. Many amps claim to sound like SET amps. SET amps sound like SET amps. Why buy a BAT and change the coupling caps and hope for the best when Scott could buy the Atma and the Audiokinesis and know he is getting excellent synergy?

I think the real question is whether Scott wants "warm and smooth" which means an el34 or 300b topology. Scott, I recommend the Atma/Audiokinesis if you are unable to audition. If you are able to audition, I recommend that you listen to BAT, Atma, an el34 and a 300b along with the appropriate efficiency speakers. Or, be patient and buy used gear and resell what does not float your boat. Good luck, Jeff
