My speakers are Paradigm Reference Studio's. I have Active 40's for the front so those hook straight to the preamp. The amp would be only for the center and surrounds, plus zone 2. The 7700 is overkill, I know. The 7125 is more what I need but it does not have balanced inputs. That may be a moot point anyway so I still may think about the 7125 if I can't use balanced cables.

An active crossover might be an option, I'll look in to them.
