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.

Sorry, but the electrons are moving and it's not accurate to say that their agregate motion equals null motion. Photons are the force carrier that move them and that's extremely important, but the motion of the electrons is what's really going on on. All one needs to do is understand how a BJT transistor works. The mechanism of their operation is the physical motion of electrons between differently doped regions. A P doped regions doesn't have photon holes. It has electron holes. The physics of a transistor are dictated by the motion of electrons.

You should call and complain about those highly capacitive squirrels running about on the power lines too.

>>>>I didn’t say there was “music signal” going through a power cable. In an alternating current AC circuit the drift velocity direction of electrons alternates along with the current. I did not compare light to heavy masses. You’re confusing me with someone else.

Stevecham, please be aware all electromagnetic waves are comprised of photons. What we usually call light, i.e., visible light, is part of the electromagnetic spectrum but only a very small part. Radio waves, gamma rays, x Rays, visible light - they’re all photons. Visible light cannot penetrate opaque materials, that’s obviously true, but obviously other higher energy electromagnetic waves in the spectrum can penetrate opaque and solid material, gamma rays, x-rays and ......electronic signals through wire.

The signals in wire are electromagnetic waves - that’s why they travel through wire at near lightspeed. That’s why telephone signals through buried copper cable travel at near lightspeed, that why there’s no propagation delay. And also why there’s no delay over cell phone systems - radio waves travel at near lightspeed in air. And what is the ONLY particle that can travel at near lightspeed in a medium and at lightspeed in a vacuum? Answer at 11. 😳
