... 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...

Hello
i didn’t read everyone’s post but I would agree with starting with clean power : independent power aka home runs if possible with good quality wall outlets ( I use the porter ports )

CABLES make a difference BUT that doesn’t automatically mean that the sound will be better or and more importantly that you will enjoy the sound better.  Some experimentation is needed !
 I approach a cable from the perspective of not wanting it... So in it goes and then I’ll listen with music that I’m very familiar with and usually I can tell immediately if it’s something I might want.  I will give it a chance and let my ears adjust but again I hoping I won’t like and then won’t need to buy it...
If you are struggling to hear a difference then effectively there’s no difference. And sometimes a cable will effect the sound that makes somethings better and some things worse - like more detail at the expense of some musicality etc.  It always boils down to what YOU Like. 
BUT Then every once in a while you try something and your jaw drops...Those OMG Moments when the improvement is so significant that you won’t want to take the cable out.

Having said all that 

I wouldn’t expect cabling to be as significant as a component change.  You mentioned using a HT Receiver as a power amp with a separate pre
Receiver’s are amazing in all they accomplish in one box BUT there not really designed to be used that way.  And it’s very difficult to get a HT system to be as good as a separate 2 channel system for music.

But that is a different discussion...

Bottom line
Cables make a difference / Trust your ears and your taste !!  Don’t fall into the trap of using cables to correct a mismatch or something like that.  Experiment !! And hopefully get to a place where you won’t feel the need to experiment...............    at least for a while lol
