Slight hum from left speaker -- Help appreciated
Two weeks ago I installed a new amp and preamp (Pass Aleph 30/FT Audio LW-1) in my system and since then I've had a very slight hum from my left speaker. It's not distracting, but it's something I'd like to get rid of. I've switched out interconnects and speaker cables and nothing changed. I did a search for ground loop hums and I could not find any useful information other than cable TV may be a problem and we don't have cable. Any hints on what could be causing the hum would be greatly appreciated. Thanks!
