Hey Leafs, did you actually try the boiling water experiment yourself? If so, that is a great way of explaining why aftermarket pc's make a difference. After many tests, and after reading many of the power cord debates, I almost automatically upgrade the pc on any new component. Even pc's in the $150 price range make a noticeable improvement.
Power cords - snake oil?
Excuse me for being skeptical but how in the world can a different power cord improve the quality of sound? I've been willing to upgrade my interconnects and speaker cables to a point and use a line conditioner / surge protector but why spend hundreds on a funky power cord ?
