I own a OneAC conditioner that's used primarily in industrial and
medical facilities. Also the Brick Wall surge protectors and power
conditioners got their start in industrial applications and later were
revised for audio use (eliminating an audible "buzz" for one).
The OneAC has a soft, but audible transformer buzz eminating from the
unit, but the buzz doesn't affect the sound from the loudspeakers. I just
place the OneAC away from the listening position, and I don't hear the
buzz. Considering the OneAC was purchased for $20 on E-Bay, I can't
complain. I'm not qualified to comment about the differences between
these and their esoteric audiophile cousins, but I suspect there isn't as
much difference as one might be led to believe.
