Jim is right in that there is not one answer for this or any question (with the notable exception of course that after the first level of upgrade power cables have zero effect on sound, ahhh, but I digress), I love Bryston amps with Maggies, but I don't own them anymore.
I like my Cary CAD 500 MB's better than the Brytson 7 Bsst that I had. I actually like the Innersound ESL better than the Bryston as well.
But they all sounded pretty darn good is the point, as did the Parasound JC-1's, lots of good amps out there. I wouldn't say one was the best, but you can have a favorite.
BTW, I heard some 3.6r's at our local dealer recently, and he had them hooked up to some Krell's, and man, that was some GREAT sound, very deep bass from Maggies, sans sub. But, he has optimal placement and room treatment, so that helps.
Anyway, good luck with the amps, you can't go wrong with Brystons, or about 10 others that I can think of for Maggies, great speakers, I'm a big fan!
