... 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...

If you are somewhat handy I encourage you to experiment building your own power cable. Solid core dead soft silver wire (riogrande.com) placed in cotton tubing (ebay) with heat shrink tubing on outside for safe insulation. Ground can be solid copper but needs to be thicker gauge to achieve lower resistance compared to same length silver. Techflex on outside. Terminate with high quality pure silver plugs. Silver is the best conductor. Cotton minimizes power storage. I was not able to find a scientific explanation why power cords have an impact on sound. But all components in my system benefited from this power cord upgrade (even turntable!) - with most noticeable improvement on CD player and preamp.

The more you spend on wires, the greater the placebo effect.

Substitute the word "more" with "less" and then it would make sense.
It's the audio equivalent of The Fox and the Sour Grapes.

All the best,

We can leave the scientific measurements to the experts but what we do know is that power cords can and do have a big impact on sound whether it's negative or positive Sometimes with power cord experimentation you can come up with a most positive outcome as if you went out and spent thousands of dollars upgrading your components. Other times certain power cords could possibly degrade the sound. I think it falls back on that cabling is system dependent.
Decibell your right, building your own power cords can be fun and save you money!

We know nothing of the sort. IF power cords affect sound then whatever causes this is measurable. There is no escaping this , this is actually something we do know.
