Amp recommendation for Magnepan 3.7's?

Rob, very interesting comments on a nice variety of amps! I've heard so many raves about the Sanders Magtech driving Maggies that I'm a bit surprised about your reaction, but have read that they have an analytical perspective. Am very interested in hearing more about the new REF600Ms as you get some time with them, not many out there yet. I run the Rowland 625 with my 3.7i speakers and find the combination superb along with a suitable quality preamp. I understand that the new 625 II is even more costly though. Good listening and please continue to share your thoughts with us, it is most appreciated!

Btw, the Bel Canto REF600M amps list for $4,990 per pair.

Rob, thanks for sharing your further perspective! I recall reading a review of the Magtech amps which came to the same conclusion as you, maybe you should be a reviewer. I haven't had the opportunity to hear the REF600M amps yet, so I find your experience with them of particular interest. BC replaced both their 500M and 1000M models with the 600M even though the 1000M amps were more expensive.
