Why Power Cables Affect Sound


I just bought a new CD player and was underwhelmed with it compared to my cheaper, lower quality CD player. That’s when it hit me that my cheaper CD player is using an upgraded power cable. When I put an upgraded power cable on my new CD player, the sound was instantly transformed: the treble was tamed, the music was more dynamic and lifelike, and overall more musical. 

This got me thinking as to how in the world a power cable can affect sound. I want to hear all of your ideas. Here’s one of my ideas:

I have heard from many sources that a good power cable is made of multiple gauge conductors from large gauge to small gauge. The electrons in a power cable are like a train with each electron acting as a train car. When a treble note is played, for example, the small gauge wires can react quickly because that “train” has much less mass than a large gauge conductor. If you only had one large gauge conductor, you would need to accelerate a very large train for a small, quick treble note, and this leads to poor dynamics. A similar analogy might be water in a pipe. A small pipe can react much quicker to higher frequencies than a large pipe due to the decreased mass/momentum of the water in the pipe. 

That’s one of my ideas. Now I want to hear your thoughts and have a general discussion of why power cables matter. 

If you don’t think power cables matter at all, please refrain from derailing the conversation with antagonism. There a time and place for that but not in this thread please.

Whoa! What? I did not know there were high, medium and low frequencies traveling through the power cord. I was under the impression it was current and voltage, alternating at 60 Hz.
That’s why we are having the conversation. Maybe I’m not understanding how power is delivered to the primary side of the transformer via the power cable. I figured a treble note and a bass note would produce different AC waveforms in the power cable. But perhaps I’m looking at it wrong. 
Why do I get the impression that Kosst and Geoff are the same person? Anyone else notice they always show up on the same threads?
