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.

I was on my phone and fell asleep to people reacting to what they see/saw, fell asleep, woke up, and I saw it differently, and never changed back to the incorrect colors no matter when/how I saw it. I really was freaky, as I was most posit e it was white/gold.

All I’m saying is that just like people still see the dress as white/gold even after being shown it’s blue/black, people’s ears also play tricks on them.

But like I said, if you hear a difference, buy all the power cords, brilliant pebbles, WA quantum chips, etc. that you want. Just don’t confuse your reality to actual reality. All it does is deter newcomers.

I feel sorry for anyone who believes that reputable high end PCs cannot improve the sound of a system in many ways--in fact, too numerous to list.

I do too. It’s like going to an art museum with your friend and being brought to tears by the beauty of a certain piece of artwork and having your friend glance at it for 1 second and say “there’s no scientific research showing that that specific piece of art is beautiful, therefore it’s just placebo effect.” To which I would reply, “Have you tried simply looking at the art piece? You’re missing out on a lot of life by carrying around that attitude.”

@mzkmxcv,

I'm not confusing anything as it was simply due to an imbalance of the white setting. All of the thousands of stations broadcasting are not entirely in sync. No mystery involved although there was a lot of blather as to what could be the explanation.

If anyone is susceptible to placebo or influence, you just admitted to it with your story of how you saw it and what you went through. I didn't.

So heed your own advice and don't confuse your reality with actual reality. All it does is deter newcomers. 👍

All the best,
Nonoise

The reason people saw it differently is not a display white-balance error, but if people thought it was in a store with Daylight lightning or 2700K-3000K lighting, illustrative comparison. Not sure if you’ve seen this optical illusion, I think I’ve linked to in previous threads, it look at this Rubix cube looking object, the “brown” square centered on the top face is the same color as the “orange” square on the shaded face, no matter that you know this, you cannot see these as the same color (if you don’t believe me, zoom in and screen shot them).

My realty is that if your upgraded power cord did nothing to the electrical output of the signal, then return it. And no @mkgus, saying a power cord did not alter the sound coming out of your speakers is no way related to the appreciation of a painting.

Power cords do make a difference; I have heard those differences repeatedly over many years. And, it wasn’t because I spent money on a cable and was determined to convince my brain that there were differences or improvements or whatever. That’s because I was able to borrow friends’ cables, relax, take my time with a variety of source materials and check them out, at length, in my system. Again, they do make a difference and, as I’ve stated earlier and will state again here, I think the electrical basis for this is that different cables provide different levels of noise attentuation, some being more or less optimal for some systems due to a particular level of noise suppression that synergizes (or doesn’t) with that particular system or component. It need not be a rocket science explanation, it can be simple and reproducible. The key is to LISTEN, although for some here, that would be counterproductive now, wouldn't it?
