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.

Can somebody just please mail the non believers a spare power cord they have lying around . Kostt , You are a stand up guy , just return it after you are done . Let's put an end to this nonsense that they all sound the same once and for all !
"Can somebody just please mail the non believers a spare power cord they have lying around ."
Could you include "undecided due to no experience"?
There is a lot of confusion here between theories and evidence. Merely having a plausible explanation for some phenomenon does not mean it is a correct explanation of that phenomenon, e.g. a suggestion that good cables have less susceptibility to electrical fields around them.  Such an explanation requires a measurement to show such reduced susceptibility of that specific cable. Then you need some proof that this interference or reduced interference is what people are actually responding to as an improvement in sound quality, possibly by adding and subtracting such interference to audio signals and seeing what people report.  
Theories and evidence ? Plausible explanations ? Measurements ? It doesn’t matter the reasons. Many of us hear these differences ( for whatever the reasons ), and actually conclude on determining preferences. If you have an interest in the subject, and would like to see ( hear ) if these audible differences exist, just try it. If you do not try it, you will not know. Enjoy ! MrD.
