... 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...

phd,  You made a statement of fact,

what we do know is that power cords can and do have a big impact on sound
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.

Logical fallacy. This is a classic example of the measurementalist's use of circular reasoning, aka "begging the question."

but what we do know is that power cords can and do have a big impact on sound whether it’s negative or positive
So , this a classic example of begging the question, I answered one with another.

We know nothing of the sort, he's assuming the truth of his conclusion.

No one expects Audio Aristotle!

When we can't make any further progress with the debate, let's instead debate how we debate.

I suppose that's why Aristotle dabbled in meta-physics.
