... 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...

Hopefully attention span of some here is bigger than a tweet (or audio forum message)
Yes! Spot on @petg60! Power cord is not the last 6 feet. It’s the first six feet. Think of it as an extension of the component’s power supply.

I quoted Wireworld's claims above. Can anybody comment on them with some reasonable degree of level-headed knowledge/insight?


That "low triboelectric noise" refers to their insulation, what they call Composilex, which they claim is superior to any conventional insulation including Teflon (from Dupont).

I don't claim to know what "triboelectric noise" means, but a quick Google search:

As for blocking outside interference, I am pretty sure they are talking about blocking stuff like radio, tv, phone signals etc. something that @boomerbillone described in very good details right above

The moment I see “I am an electrical engineer”, I stop reading right there 😂😂
Hi @mahgister:

You are 100% right! Nobody can change their beliefs. They will Google the s%#*^t out of Internet to find pseudoscience stuff to support their beliefs. Or is it religion? And forget about listening or trying. They would do nothing of that if it goes against their beliefs. Even if it were free.

.... I cannot change beliefs.... 


Nope! I cannot let that happen! I cannot let the unscrupulous cable manufacturers take advantage of the poor souls. I must stop this 😩😩🤯🤯
I really want that good Google machine someone owns here. Master googler. Who needs brains? A nice Google machine does it.
Do all the research you want. Nothing substitutes trying for yourself. In your own system, with your own ears. Research is good as long as it leads to picking something to actually try.

There are people like this one above you who do “research” all day, every day, and try nothing. For some very strange / weird reason. That’s the very definition of narcissism 😂😉.
Timely and relevant (for this thread) is what Paul McGowan posted today on his newsletter (copy / paste):

I had to smile while reading this comment to a recent video: “I agree with most you say….except about the wires and power cables….but I still subscribe and like! so there!”

Yes indeed. So there. This issue of wires and cables making a difference for some and not for others is one of continual fascination for me. It begs a twist on the age-old question about trees falling in woods without anyone hearing them.

“If I hear cable differences in my system and you are not around to listen, can you make a sweeping edict those differences do not exist?”

Upon questioning cable deniers—their angry eyes ablaze and pitchforks raised high—most admit they’ve never actually tried comparing cables on a resolving system. To them, it just cannot work. There’s no need to actually see for themselves because that would be the height of foolishness—like testing the efficacy of gravity whilst standing atop a ladder.

And so the fallback position is to demand proof before they will consider it.

I am guessing an overwhelming fear of being called out as a fool is the key motivator of cable deniers—understandable as no one wants to wind up in a vulnerable place.

And still, what is true continues to be true despite our beliefs and disbeliefs: trees fall in the woods, rivers run while we sleep, cables matter on resolving systems.

Do people still read textbooks?
Nope! One Google Machine and done! If it is in the internet, it must be true
An interesting creature you are Dow Jones. You think you are smart don’t you? You might have a serious case of code I.D. Ten T problem 🤘
