I'm a fan (and owner) of SimAudio products. I am currently using a Moon 600i integrated (which I got for 5k used) with Kharma Ceramique 3.2 FE's, a not particularly "forgiving" speaker with great success. I can't weigh in on how it would work with the Maggies, but if you have a dealer near you I'd have a look and listen. I like the ModWright suggestion as well.
