Scottlanterman - I read very positive review of Atmasphere (MA-1) but what makes them hot is amount of current that tube heaters consume. Each tube is about 6.3V 2.5A and there is 28 of them total. That equals to 441W dissipated power just for the heaters. Total power dissipated might be in order of 1kW.
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.
