Can a better power cable make a difference if NOT plugged directly into an outlet?

I am curious about improving my sound with power cable upgrades.

At present, I'm using a setup which Almarg (RIP) used and which he recommended to me:

Wall outlet (hospital plug)
Audience Adept Response-ar2p power conditioner
Wiremold strip w/ Shunyata defender

I use Pangea AC 9 SE and AC14 SE cords, at present.

This setup has been quiet and hum free. 

Still I'm curious about whether better power cables might make some improvements, here or there.

The question is, whether any improvements a power cable could bring would be blunted or nullified by the setup I'm presently using.

Any thoughts?

Those who say power cables never matter, please go watch a cute cat video instead of posting here, please.



Great advice, here. Summing up:

I will ask Audience their opinions about cords.

I will not try a slightly better cord. I will step up significantly to try something much better.

I will try both via the conditioner and straight to the wall.

I will try things one at a time, with different components, to see where the greatest differences lie.

I will not hesitate to call "no difference" if the difference is not forcefully present.

I understand better that "noise" is not always the overt, obvious kind. This is about the differences made to the background, which may already be fairly quiet but when it's made even quieter, the audible sounds will improve as a result.

Additional notes:

My wall outlets are "Porter Ports." They're supposed to be pretty good.

My Audience plugs directly into the wall. There is no place to insert a cord, there. The wiremold strip plugs into the audience and then serves everything.

So, there may already be something to improve, there.

In my new room, I hope to plug things in, thus:

Dedicated outlet #1 — monoblock amps (left and right)
Dedicated outlet #2 — source components (streamer and DAC and CD transport)
Dedicated outlets #3 — subwoofers 1, 2, 3

Power cables do not make a differrence.


Until you plug it in and turn on your components =D

@hilde45 I have used several different Audience power cables over the years. Starting with their original AU24 powerChord. Excellent cables that work well on DACs (medium power AU24se) and amps (high power AU24se). I was not as impressed with their lower end Forte F3 though.

I like your plan to step up significantly. That should make the difference more obvious. 

+1 on rhodium plating...took some getting use to.The burn in time is crucial.Once the flip flop is done.The tone is clean, no glare.Been gold guy forever and i think a  mix is more musical
