Thanks for the input guys. I have to say, I tried the Bybee filters on speaker cable before, and was disappointed - but it could have just been system synergy or something. Also, for reference, I'm using 47 Labs OTA Sakura cable for interconnects and SC, FIM Gold PCs for amps and Shunyata Sidewinder for preamp. I'll check out the conditioners you mentoin. Thanks again,
John.
