... 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...

You see the human wave at the stadium? Everyone is at their seat but the wave propagates forward. This is how music propagates down the wire. The electrons are not going anywhere but we hear music. At the stadium, there are big guys, small guys, thin guys fat guys, some standing and some walking. These are noises and that is why we never see a perfect human wave. In cables, the electrons are boxed in. Some electrons can move freer than others; some ran into obstacles (impurities) and some forced to move in different directions (external interferences). These are noises as well and that is why we don’t get perfect music. And that is why we get different sound using different cables.

Make sense?
Make sense? No
This is about power cords music doesn't propagate down power cords.

LOLZ noise floor -175dbz.   What do you think the noise floor is in your listening room (house) with everything off?
Measurements do not tell the whole story. Play A note with a cheap violin the meter will show 440Hz. Play the same note with a Stradivarius the same meter will also show 440Hz.
Verdict? Trust you ears.
