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.

Congratulations on acquiring the MA-2 amps! Hope you enjoy them as much as we have here; I cannot imagine ever going back to a tranformer coupled amp after living with these beautiful OTLs.

I drive mine with an Aesthetix Io Signature (with volume controls) using the single-ended RCA outputs (gasp) to great effect. I have yet to try them with a balanced cable so I don't know if that would improve the results I'm getting, the single-ended sounds so doggone good.

One thing that has made a very handsome improvement, however, has been the change to Sylvania 6SN7-GTAs for the input stage. This seems to be a very nice combination with these amps.

I'm with Rushton, I don't expect to ever try any other amps as my M-60's work so well with my Köchel K-300 horns which I don't plan on changing either. Unfortunately I can't speak to the question you've asked. I can say that Atma-Sphere preamps offer truly outstanding performance.
Hello,
Another congrats on your purchase. These amps took my system to a completely different level than anything prior. I'm using the MP-1 preamp and couldn't be happier. These components together really do synergize nicely as they should. World class sound, tubes and built like the proverbial brick outhouse. How can you go wrong?
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!
