... 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...

PCs are going to have less of an impact on the sound of your system than ICs or speaker cables. Optimize after those are set.
Not if you have such an oddball PC that has a characteristic that permeates the entire sound, which is what the OP has.

So much of this is system dependent, but so much is dependent upon the power cord's design.
I, in all honesty, never thought power cords would affect the sound of a system until I auditioned some AQ power cords.

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.
