Try the cheap clear damper rings from Audio Research. If you don't like the sound you are not out big bucks. I like what they did in my system. They should make the biggest difference in a system that really moves alot of air. Also try a Bright Star Audio Air Mass under your pre amp, as well as your CD player. Isolation seems to be the most overlooked "tweek", every one is into the AC( power cords and conditioning) thing right now as the hot topic. I'm not to say that isn't important. If you have real bass you NEED to isolate and damp vibration. Try it!
