... 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...

I'm new to the whole power cord thing too.
I've been learning quite a lot in this forum about how the power cable affects performance of the devices they power.

One of the first ideas that I hadn't even considered is the fact that the power cable is pretty much somewhere  in the middle of the circuit past the circuit breaker.

Alternating current goes through a conductor of the Romex in the walls, to the outlet receptacle, through the power cable plug, through the power cable, through another plug, into another plug in the device requiring current, and to close the loop for the potential, through the other pin in the plug on the device being powered, into the plug on the power cord, through the cord, to the plug into the outlet receptacle through the other conductor of the Romex in your power box.

The AC power has 4 connector points through which it must travel from the circuit breaker to get to and from the device requiring current, not taking into account the ground. The materials and quality of those connections is also a contributing factor.

This is why I must logically agree that running dedicated power runs (also isolating it from other devices in the home), and higher grade plugs will allow for better electrical connection, plugs at the wall and plugs in the cable where any deficiencies can be overcome.

I wanted to discover for myself if any benefit could be observed by changing my factory issued power cord out for something different? I can't remember names, but a few suggested Synergistic Research Master Coupler as a good start for a test.

The Master Coupler X2 did improve the system sound when I plugged it into my power amplifier. I was converted to power cable upgrades, because my ears told me there is something to it.
