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.

I own the Audiokinesis Jazz Modules and have heard them with the S-30 amp. I believe Duke even voiced them with the S-30. Atma-sphere amps have a high output impedance (the S-60 is 4.1 ohms). I think one of the reasons that Atma-sphere and Audiokinesis are a good match is due to the impedance (no lower than 8 ohms and closer to 12 ohms) and smooth frequency response of the speakers. I currently use mine with VAC Auricle Musicblocs.

Personally, I've never liked tubes and Spendors and I've owned a few pairs of the Classic Series (the Jazz Modules replaced 1/2e's). If you are considering selling the Spendors you could do a lot worse than an Atmas-sphere Audiokinesis combo.
