A few years ago I bought the Infinity CC3, a pair of RS5's, and a pair of QPS1's as surround speakers. For some reason my CC3 sounds dull. I tried adjusting the brightness levels to the highest levels, and it seemed to help a little, but it just doesn't seem like dialogue comes through clear enough. I'm setting my center channel to a higher level than the others, but then I don't get as much effect from the other speakers it seems. I recently purchased a Pioneer 563A and an Onkyo 501 receiver to replace an old player and receiver. Would a digital or optical cable for the DVD to Receiver help out at all? How can I get my center channel to have louder and clearer dialogue? Thanks!
