I count seven speakers in your system. Plus a sub I'm assuming? It just so happens I run Classe with Thiel in my H/T system, and I own a CA301 that I use to drive a pair of Thiel 3.6 speakers in my bedroom, those speakers are rated 400 watts @ 4 Ohms. The 301 gives them the business nicely.
Now let's talk H/T. I just picked up a CAV150 which I will use bridged to run 3 Thiel MCS1's in the front (L, R, C) That's good for 300 x 3 into 8 ohms. Doubles into 4 ohms. These particular speakers are 400watt four ohm 90-dB eff. And brother that's plenty of juice.
I guess you could bridge two channels for your rear's and run your sides at 150 watts per channel. That would account for all six channels on the CAV 150.
The 301 is a monster but I'm not exactly sure what your ML mains are rated for. I here ML's need a lot of juice. That's your call, but it would be a little hard to imagine those two amps not doing some serious ear damage when run together in that configuration. Worse case cinario is you add one more ca301 and by-wire the mains. Do you have a sturdy rack? I hope so. Also think about the CAM 350 monoblocks they have some zing. Anyway I'm rambling again good luck and let us know how it turns out.
