I'm in the process of putting my system together for real after years of having my equipment partially assembled. I'm wondering if anyone has any recommendations as to how to utilize the equipment I currently have, and what equipment I should purchase to round out the system. Here's what I have to work with: Yamaha DSP-A3090 (7 Channel)Processor Klipsch Epic CF-1 Main Speakers Klipsch Heresy HFB(Purchased 1980's) Rears Klipsch KV-3 Center Channel Boston Acoustics CR400 Powered Sub I currently have no front effects speakers and would like any recommendations on these. Also, The DSP-A3090 can handle another center channel as well as another sub. Is there a center channel that will compliment the KV-3 and another sub to compliment the CR400? Thanks in advance for your help. J.
