    Atma-Sphere MA-2 Amplifier

    I think we need to spend more time on the Atma-Sphere MA-2 Class A, 220 watt, OTL amplifier.

    From these reports and WBF members' reports there seems to be a consensus that these amplifiers, like other OTL amps, are capable of amazing transparency, but, unlike other OTL amps, you can get these in 220 watt and 500 watt versions.

    Power consumption 800w per channel. Wow, I thought my Line Magnetic put out some heat but this is something else !

    I owned MA2 Mk II.3s for a number of years and I loved them. Never a glitch with a tube or any other issue for that matter...Problem is I live in Texas. In order to be comfortable I would have to turn the ac way down a few hours ahead of a listening session in the summer...In the winter the amps pretty much kept our house cozy when the amps were on...
