Hello from Canada. Very pleased with the Cambridge a/v receiver, in most respects. I have a question (and I did do a quick search on the threads here first, but not a lot of info). I plan to use a separate amplifier to power the front left and right speakers, and use the Cambridge for the center, rears and digital signal processing. It's not exactly clear to me where the separate amp plugs into the Cambridge. It's probably obvious to the rest of you! Thanks for the help. J.
