I beleive that both of Atma-sphere's own preamps are fully balanced, and I would imagine that they would be a perfect match. Please keep in mind that I haven't heard them, but it would stand to reason. Good luck and happy listening!
Balanced preamps with Atma-sphere MA-2's
I just purchased a pair of Atma-sphere MA-2 Mk. II.3 OTL monoblocks (thanks Siddh) to drive my Dynaudio Confidence C2's. Right now, I am using a single-ended SAS 10A tube preamp with pretty darn good results. But, Ralph at AS and Brian at Essential Audio state that the AS amps really need a balanced preamp to shine. What are you MA-2 owners using for a preamp? TIA.
