Good impedance match for Atma-Sphere MP3?

JT - I have a brouchure that came with my recent MA1's that lists the MP-1 pre is remote controllable. In talking with the factory, they are working on getting it done, (at least in the MP-1, not sure about MP-3) I believe an MP-1 will have to go back to he factory to get the remote motor option installed, but the mounting posts are already there, at least in MKIII units, I think I remember hearing. Did you see the recent soundstage review of the MP-1?

Bill, the S-30 won't drive Wilson Sophias well, but MA-1s, especially Mk IIIs, will do a wonderful job. A pair of M-60s could be used if budget is limited but you'd likely want to use a pair of ZERO autoformers with them. The MA-1s will do a better job all around.

Disclaimer: Atma-Sphere dealer.

how much is the remote option though?

Essentialaudio (Brian?), I really appreciate your insight -- the fact that you're a dealer only adds credibility to your advice -- presumably you've heard the various amp-speaker combinations and know what works. I'd initially confused (cost-wise) the MA1s and MA2s -- was pleasantly surprised at the cost:value equation of the MA1 MKIIIa. Thank you for recommending them. Until a year ago I'd had no experience with Atma-Sphere -- In addition to his works of genius, I find Ralph's accessibility and warranty policies just amazing. What a great company.
