What's your source component?
Just a guess, based on lack of specifics in your post, but I think you might have room acoustic problems, and need to work with speaker placemant. Another possibility is an ac problem. Get a voltage meter and make sure you have enough current.
its a rotel 971
The nordost ECo antistatic spray make a remarkable improvement for me it's got to be the best sub $100 tweak I've tried. Use it on top of CDs, on spreaker and IC cables and power cables.
