I wouldn't be too sure. My understanding is that only the "power regenerators" such as those by PS Audio actually do the job that your friend needs done. I could be wrong.
If you have a line conditioner, does noise matter?
I have Belkin, BPT and Brick line conditioners. I have a friend that says his electricity is "noisy" due to garbage on the ac lines and he claims that he can not listen during peak times and can only listen late at night.
My understanding of these various line conditioners is that they control spikes and brown outs to keep the volts at 120 +-. Shouldn't this take care of the ac "noise" on the lines allowing only the music to flow through unimpeded?
