Nothing in High end equipment cleans up what comes out of the wall. However not all power conditioners are created equal or do they all really condition. I would not put standard conditioners on amps. I might put them on purely digital equipment such as dvd, sat. ect. I have an equi-tech system which is balanced power and not exactly conditioning. It provides pure clean balanced power without messing up good amps with conditoning that often impacts the full range of output to your speakers.
