Dek,
I have T5's up front with an M5 center and four L5's for surrounds. I just bought the second pair of surrounds and am waiting for the new 7700 to decide whether to buy it or get a couple more monoblocks. I also bought a second A1 to run the T5 subs in stereo since I do about 70% of my listening in 2ch where it can sometimes make a big difference. I bought the M200's kind of as a holdover from my 2 channel days when I almost always ran a couple of big monoblock amps. I like the effortless quality they can have with demanding or complex music.
