... 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...

Or if you mean the cord plugged into the wall...it takes the electricity from the wall to the amp/components.  No audio signals run in the AC power cord.  As long as it's fat enough to handle the current you're good to go.
It does not.

As long as your cord is thick enough (low resistance) for the maximum power of your load, power cords do not in any way affect the sound. Think about it..... you are constrained by the romex house wire coming to your mains outlet from your main panel.

A 14/12 gauge mains wire will be more than adequate for 95% of home audio (15 amps at 120 volts = 1800 Watts, https://www.cerrowire.com/products/resources/tables-calculators/ampacity-charts/ ). If however, you have a gazillion watts/channel amplifier, even the thickest cord will not save you. Then you are effectively running a welding machine and you need to change your mains panel and all the internal wall wiring of your house.

Otherwise, it is just snake oil.
