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.

There was a time when the high end manufacturers did not supply iec power cord inlets ( they were all hot wired ) on their equipment. I have not seen a high end piece as of late that is not equipped with an iec inlet. What does this tell you ? Enjoy ! MrD.
"Audio on the cheap' site. YUP! I just bought a pile of Pangea AC14XL BECAUSE THEY ARE ON SALE..            
Particularly exciting was the sale prices are 'reasonable' cost instead of the staggered crazy regular price. I had wanted some 4m LX but balked at the odd overcharge for it. With the sale they were 33% off. Sine the have pure copper plugs, I thought yeah go with my pure copper duplex!                   
I would not recommend the AC14XL for amplifiers though.                                       
I just moved my Amp power cord from the dedicated Furutech GTX-D NCF Rhodium outlet to it's partner, a Furtech GTC-D Gold duplex to change the sound. It changed. I am certain this fact could melt nonbelievers brains into puddles. Except they are so certain I am hallucinating..... and they are not. sadly for them, they are wrong on both counts.

The Rega Osiris integrated comes with a very juicy pc. It’s got their name on it though I’m not sure if they make it. PCs make a difference but at a certain point it’s diminishing returns unless money doesn’t matter and if it doesn’t who cares.
