... 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...

He is a great dac designer but he is sometimes very surprizing for me and i learned listening to him or reading him few years ago....Especially about noise. and what is audible by humans...But many things he say pass over my head.... :)

I bought a dac so good i never look back.... Then i read no more to understand this technology.... :)

Noise floor is meaningless without knowing the distortion spectrum.

Let's start at the beginning....... oh yeah,  the Power Cord.  Expect it to "probably" sound different.  If it's better, you win.  If it's worse, give it back, (if possible).
