especially if you have contemporary non-audio appliances that may be strong RF noise sources. Things like digital video recorders (TiVo and the like), microwave ovens with complicated controls, high-efficiency furnaces, personal computers, garage door openers with rolling codes, etc., etc., all seem to contain switching power supplies for the computer controllers these days. They generate a lot of RF noise and put it back onto the AC line.In-line filters for these things can help a lot. Many surge protection power strips also contain EMI/RFI filters.
