More than any other audio component, I remain perplexed by audiophile power cords and the clearly audible effect they can have on not only a system’s sound quality but also their ability to enhance the engagement of the listener.

Considering that power cords don't carry a music signal but rather a 50/60-cycle sine wave along with its harmonics and other AC related noise, other than a lower noise floor I can’t see how aspects such as bass, treble, soundstaging, imaging etc. could be so altered. But there it is. It’s plainly obvious to anyone I‘ve sat in front of a system while swapping out power cables.

I don’t quite understand the actual mechanism responsible but it is plainly more than resistance, capacitance and inductance. As a reviewer all I can offer is my eyewitness account. I’ll leave the techie explanation to others better equipped to explain how a mere power cable can have such a dramatic impact on music playback.
