2 Classe ca 100's vs 1 Classe ca 200 ?

go for one. you'll win in better tonal balance, less distortions and less speaker load complexity.

I second Marakanetz advice. I've found a more powerful amp will sound better than bridging two amps.

with what you're looking for, you may even consider going with the ca300 if you can, i've read that the sonics and low end are much better than the 100 or 200. it may be stretching your dollar, but it's a thought. looked into it quite a bit as i was consering these amps until i went to a tube amp. good luck!

This is interesting. Folks feel a stereo amp is preferable to monoblocks, is that what you are saying?

I'd go for 2. I have a CA200 and it's a great amp. But, bridged it is like 700w into 4 ohms. The 2 CA100s also give you option of vertical biamping, plus bridging option. You may also find one CA100 is plenty of power for 7Bs.
