I have Magnepan's $550 MMGs on the way pretty soon to play with (to see what planars sound like), in anticipation of upgrading my system. I've put some thought into the speakers and have a short list of demos, but thought I'd also think about the electronics. I'm currently running Outlaw gear - 750 pre/pro and a handful of M200 monoblocks. My source is a Denon 2900 universal player. I recently sold off my Paradigm studio 100s and 20s. My question is this: I may be able to upgrade both pre/pro and the amp, but right now I'm assuming only one upgrade for the time being. With that said, which would make the most difference? Would the M200s with a better pre/pro be superior to the 750 with a better amp? Or the other way around? I am about 75% HT, but I want to incorporate more music listening into my days, so the HT percentage may change.....If it helps, assume for now that my speaker upgrade will either be to the Paradigm Signature line or the larger Maggies. I know the Maggies will require more juice than the Paradigms, but I'm talking just in general terms as far as upgrades. I'm thinking a 3 channel amp would be best, with the M200s powering three or four surrounds. So if you have any recommendations, please fire away.....thanks!
