... 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...

"All I was saying is this is an opinion "we" don't know any thing of the kind. If this statement is true then the reason for it is measurable, the power cord has some anomaly"

dowjones,
As I've stated before, I suspect some day science will catch up to our little hobby & figure out what measurement accurately correlates to what we hear with the human ears/brain.

They haven't yet.    
I am electrical engineer . Auburn University (War Eagle). Can't really see advantage of "super" power cables. That being said, I did buybuy: https://www.pangeaaudio.com/Pangea-Audio-AC-14-Power-Cable
Because they look cool. That's it, the look cool.
The moment I see “I am an electrical engineer”, I stop reading right there 😂😂

Try to avoid products that are built by the cheapest bidder.  Good companies will not sacrifice a few dollars to mask the sound of a great design.
