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.

@mrdecibel : " I will avoid and ignore them whenever I can"

That seems disproportionate to the issue at hand. Someone who will never believe in the benefits of power cords may share other mutual beliefs and experiences and may also have something valuable to contribute.

And that also speaks to the brand "naysayer". As well as my question about $22,000 power cords (nonoise). Which, by the way, is not a straw man argument at all. The point I'm trying to make is that there comes a point at which all of us will become naysayers. And while $22,000 is an extreme example, a $500 power cord sounds pretty extreme to the person who looks at the beefy power cord that came with his Mark Levinson amp....at no additional cost.

 And that is not to mention that we could be having this same conversation about little blue decals that we stick behind curtains and pictures on our walls that improve the SQ of our system. I'm sure there is some 'science' behind these as well. I'm sure we would have fervent debate about the nature of that science that would yield no consensus. And there would also be people who say that they can here the difference and that they are reliable in their observations. 

Also, I appreciate your references for affordable aftermarket cords. I will look into them but if you've followed my leap into hi-fi you also know I'm a cheap bast@rd. Heck, my DAC only costs $110. But I will tell you, last night I almost got up and put in a cheap power  cord to my amp. The only thing that stopped me is how much trouble it is. The amp weighs 95 pounds and is on a component stand that can't be moved without pulling the amp all the way out....not to mention the tangle of cords to sort through.

However, I am building built-ins soon and it all has to come out. I'll either do the test then or maybe even try a cord you recommend. I'm not sure that the cheap cord vs OEM cord is a god test. Naysayer that I am I fully believe that a cord with insufficient current flow could affect how an amp operates.

Finally (I'm sure no one has read this far), I do not know who assembled my system; the original owner or an expert adviser. Could have been either. The cousin in question dives real deep into stuff so I would not have put it past him to have done the legwork.
