McIntosh 501 or 602 for Magnepan 20.1


Has anyone tried any of the big Mac amps with Magnepan 20.1? I'm in the search for an amp. I'm considering:

Krell 400/450
McIntosh 501/602
Rowland 302
H2O Signature Mono

I'm running an Audio Aero CD player so no preamp is involved. I have heard to bypass the H20 and Rowland since I don't have a preamp but I haven't had a chance to try it in my setup.

Thanks...

Have you considered the MC2102 100 watt tube amp? I've heard this with the 1.6, 3.6, and 20.1. It's a fantastic combo. Also, the MA2275 integrated is another nice tube option from Mac. Maggies just love the tubes!
MC2102 on a 20.1? I dont think that would be a good idea, my 3.6's clipped my 1201's! As for the 2275 I dont think it could properly drive a 1.6 or higher...maybe the MMG or 12's.
Clipping point has a lot to do with room size. If your room is large, that last 3dB of volume can eat up a lot of Watts - even 1200! Arthur
I power my MG-20's with a combination of Threshold SA-1s with a Pass labs 350.5. The 350.5 sounds great on these speakers and powers them effortlessly. So even if you are not going to bi-amp your maggies I would suggest you add the Pass labs 350.5 to your audtion list. I see no problems because of not using a standalone pre-amp in your setup with the 350.5. Good luck in your audtioning ,your MG20.1s are amazing speakers!
