I spent a bunch of money of power conditioners and products since my power has some EMI issues. Turned out I also had a bad tube in my preamp that was causing a bunch of noise in my speakers.
The conditioners worked to lower the EMI noise but didn't do anything for my bad tube!
I should clarify, that my listening room is a little room in my basement that the last owner put on the same circuit as the room above that is now a nursery. I seem to be running into issues as more items are running in the nursery. Physically running the wire from the panel to outlet would be super easy in the basement.
@bazelio told me he ran a separate circuit for his audio room.
I'm working on this now. Getting electrician quotes and will pick one soon. Check the power conditioner thread for more information. Some helpful responses when I asked a similar question.
I thought this was going to moving into audiophile-pole district, and I was getting ready to guffaw and pour scorn. But... If you have other devices causing audible noise, or even switching noise, and it can be avoided by running that cable --- do it!
40 years ago, the father of a friend of mine ran a recording studio in his house. Fascinating stuff, including a disk cutter! When he was recording, the whole house had to observe electrical silence: no switch could be touched, and some stuff just had to remain off.
If it's really easy to run the dedicated line, I wouldn't even think twice about it. Do it. Report back on the before/after effects. We'd love to read about it.
