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.

Why would multi-thousand dollar components come without adequate power cables? In fact, presuming power cables do make a significant difference, why wouldn't a $5-10k amp or pre-amp have just exactly the right power cable for its specific design? Why would a component maker spend so much design and construction effort on a unit and then send it to you with a crappy cable? That would make me wonder where else they are cutting corners.
Why would you jump to the conclusion that they’re cutting corners. I’d say the evidence is actually that many if not most high end amplifier manufacturers are blissfully unaware of aftermarket power cords or, in some cases if they have heard of them they don’t care. Now, one reason they might not pursue power cords is every customer is different, so no matter what power cord the manufacturer provides folks want freedom to choose their own power cord. Same thing for fuses. Why should manufacturers pay for something that’s going to be replaced? Doesn’t make sense.
