... 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...

A fuse is necessary for the amplifier to work...
If the fuses modify the amplifier working and not only enables it,
Then the amplifier is broken,
Because the fuses cannot makes the amplifier works and modifying it at the same times....
But wait a minute, is the working and non working of an amplifier are not also a modification of the amplifier?

Your argument is not an argument sorry.....It is a mantra, a disguised opinion but definitively not an argument....

By the way i dont have any experience with the changes of fuses in a piece of audio....My opinion is that there must be differences, but my opinion is only that, my actual opinion, not an argument because i never try or experiment it....

Actually a fuse is not necessary for the amplifier to work it's a safety precaution.

:) my own ignorance ....

You are right for sure a fuse is not related directly to the working of the amplifier....

but that does not change the fact that anything that is in the audio system or in the electrical grid act on his own increasing or decreasing the noise floor...

Be it  even some passive minerals or an electronic component....

Electronic design on this perspective is an art of the trade-off....

Once the noise floor is beyond a humans auditory perception does it really matter if it gets any lower?

Nobody hears the noise floor directly...

We hears a modification of the sound coming from some noise ocean floor so to speak....( the electrical grid of the house is an "ocean" of noise )

When engineer design the electronic component they do so trying also to decrease the noise floor of each electronic components composing an amplifier or a dac for example... It is always a trade off, because ANY new component will work but with a cost of his own in term of noise...It is a compensation business for the engineer to controls the effects of the noise....

Like you already know i am not a scientist, this is my experience and reading...
