... 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...

High quality power cords do not impede power to the unit hence high impedance/low impedance with the root word being impede
if power is less impeded to the component the more stable and efficient the signal from that component will be    At least this is how it was explained to me
good luck

Wow, the website lists no prices and no ability to purchase from there, no dealers listed or found when googled. Saw some older reviews and one forum showing some prices from 2017. Definitely on the upper end of the spectrum, but not sure which of the three series shown on their website that could have been. Liquid state is definitely different, though I wonder what the conductivity of the medium is compared to copper.

Can we think about this logically (can we?)?

So long as the metallurgical properties of the cable are capable of carrying the AC, and so long as the size of the wire is sufficient to the current draw, then it seems to me that the ways in which a PC can affect the component being powered by it (and possibly components downstream) are two:

* the cable is acting as some kind of filter on the AC it's getting from the receptacle

* the cable is acting as some kind of shield that is rejecting some kind of outside electrical interference

What other possibilities are there?

The cable could "starve" the component which would affect the sound but I don't think anyone would want to go that route or shouldn't. Rejecting interference I don't get since the main is filtered by the components transformer and capacitors or should be.
