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?

While is doesn't adjust line voltage, a sub category of power conditioner includes an Isolation Transformer.
My PanaMax has all the usual power conditioner claims but also has a 400va iso trans. Into this, goes all my low power and digital equipment.
If I could have found the Furman Elizabeth refs, I may have gone that way. As it turned out, the Panamax was available. Not inexpensive, either.

Many, if not most, amps DO NOT like power conditioners. My experience has been mixed. My Rotel RB-1070 really hated the conditioner. My ancient Carver cube? Seemed good with it.
My PSAudio ICE integrated likes it too, but has its own circuit and Solosist outlet.

It would be wacky expensive, but couldn't a motor driven Variac be used to automatically control output voltage to 120, or whatever desired?
