Chang lightspeed VS ESP powerdistributor

The outlet will be better.

These devices are not in the signal path and will not improve the sound of your system. This kind of product is a hoax. I am not exagerating. Ironically, power amps are a source of power line distortion rather than a victum of it. The power supplies in you equipement have very large capcitors and regulators that due all the filtering you need. Nobody makes gear with such a poor power supply that it is effected by irregularities on the power line. Honestly, go to WalMart and get a power strip. If it makes you feel better get one with some surge protecteres in it. Spend the money you save on good music.

Guys, as I said the power amp is a source of power line voltage distortion and not a victum of it. A power amp distorts the line voltage by the very nature of its operation. If you had any idea how a power amp works you would not make these claims. If you could see a picture of the current delivered by the power supply rectifiers to the filter capacitors you would see that it does not look anything like a sinewave.
