Thanks for the tip. A friend of mine recently suggested that same solution, which I'd never thought of before. But unfortunately, the HK 110 doesn't have pre-amp outputs. Nevertheless, it is a good solution and frees me from having to worry too much about the current capacity of my next receiver. In fact, I've just about decided to go with another HK, the 230, instead of the CA. I like HK and the 230 pumps 35 amps of current. That should be enough even without routing the fronts through the Rotel (because I just don't have enough outlets to run everything at once).
Incidentally, my friends were right about the center channel. I auditioned it at home and the system seemed to come up to speed. Could still use a little more power though.
