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.

It's not that we only want to hear what we agree with, it's that it's great to keep it civil. 
Well, that it is honestly debated shows it isn’t a generally accepted notion.

I believe to have heard a slight difference, but could not say anything beyond the subjective.

I speculate that “noise” is the issue, more so than fabrication or design.

If you're feelings are hurt or you are embarassed, uncomfortable, or confused by simple, demonstrable, and obvious truths then I would say you must not have tried better quality power cables as have others here who have reported they're experiences so I suggest, encourage, and recommend that you try to improve the low quality cables that it appears you are using based on your language here. The extraordinary performance of my primary music reproduction system is very much built on the foundation, basis, and science of the Aluminata AC cords that I referenced previously in this thread.

that it is honestly debated shows it isn’t a generally accepted notion

The simple fact and truth as this thread has plainly shown, demonstrated, and revealed is that it has not been honestly debated there have been trolls, self-proclaimed "experts" and "authorities" who have infiltrated this group/thread to disrupt, derail, and prevent the discussion of the various options and choices for quality power cords such as the  Aluminata AC cord and there is universal agreement that these cords make a difference by those who have experimented, listened, and tested these alternatives with the exception of those who are blinded, consumed, and vulnerable to their own preconceived bias, prejudice, and delusions with the exception of those who lack music reproduction systems of sufficient resolution, signal to noise ratio and/or dynamic range  to demonstrate such results and the proof is in the many posts that the moderators have deleted and I have reason to believe have even banned from the group for their ignorance, provocations, and defiance of this forum's rules, guidelines and policies.
