... abit confused: how does a power cord affect the presentation of sound...


Hello to all...

I was shifting around components in my system, trying to squeeze out better controlled bass, more definition within the soundstage, and better define the "voice/midrange" presentation...

I presently have a tube preamp (hardwired with a wall wart) into an HT Receiver; source is a Marantz SA-8001 CD Player

Swapped out a Yamaha HTR -5550 (hardwired) for a Parasound HCA-750A (which needs a power cord).

CD Player is powered with a PS Audio Statement SC power cord, so I went in my closet and pulled out another PS AUDIO Statement SC power cord, hooked it up and expect to give it at least 5 days continuous re-break-in before serious listening.

Took a minute to lookup reviews about this power cord - and I read some rather confusing reviews: some luved 'um, some liked 'um, but some thought them " ...slow... " (?), and giving a veiled presentation...

I'm gonna listen and decide myself - but I'm abit confused: how does a power cord affect the presentation of sound - I know that interconnects and speaker cables would/could/Do affect sound presentation - but how could a power cord?

Explanation/thoughts please...

You're not the first to post that video I've watched it a couple of times. It just doesn't tell us anything other than how to make a good antenna.
This conversation is like reading the Bible. One story but several interpretations of of it. If you already feel that it doesn’t help because someone told you it doesn’t and you didn’t experiment with YOUR OWN SYSTEM, there is no convincing or changing ones’ mind to do so. I’m not here to persuade anyone one way or another. It’s your choice. Remember, I said, “with your system, do with you want with it. What ever makes you happy about how you justify or spend your money. As long as you are happy with it, that’s all that matters because at the end of the day you paid for it. I definitely am enjoying mine.”😀 been listening for 6 hours and counting 😀😀
What did the video show you? I saw how to make an antenna. Did the RF picked up by the cheap cord affect the sound? Why do you assume I've only had 1 set of cables and never tried others? Noone told me anything. You jump to a lot of conclusions. 
it has a profound effect on the sound by the simple virtue of allowing electrical current to flow into the equipment. Then the unit can be "switched on" and start to reproduce music .It is a KEY piece of the hifi food chain.

That said we humans still have no idea what 60% or more of what the universe is made of (dark matter, dark energy, black velvet ??) so everything effects everything. I have a nice $200 Steve Cullen AC cable that absolutely sucked the life out of my amp. It was replaced with a 20 dollar hospital grade green dot cable that dropped the noise floor  to the sub-basement and added some luster to the amp, so go figure. $50 plus shipping will get you that Cullen cable if you are interested.
