I have the same problem but I don't have tubes. I have tried many ways to get rid of this noise even a b-p-t power cleaner and no success. So I'm still working on it.
Please advise - volume-variable buzz in spkrs
Introduced a new (used) tubed preamp into the system yesterday. Having had tubes before, I was prepared for a tube hiss, but what I got was a buzz that increases with volume. It is in both speakers and seems to be about the same level in each. It definitely gets in the way of the music and during a late-nite session could be heard even farther away than the listening position.
Nothing else in the system has changed. I use Chris VH power cords on the cdp, amp and preamp. I tried lifting the ground on the pre and amp (separately); tried a cheap 2-prong cable; no change. The HT comes through this system, so I disconnected that including the cable tv. No change. The only thing I haven't tried, I think, is changing tubes, and that's because I don't have replacements on hand.
Any ideas? I've been thru the forums here and on AA (but not fully; my DSL chose this morning to crap out as well!).
