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.

The age old debate. The only way to find out is try it, if you can not tell the difference then send it back. 
 

@lemonhaze Thanks for reaffirming. I'll take a look. When I see hyperbole or exaggeration, my hackles are raised so your additional credence is helpful.

@recklesskelly Yes, "try it out" is good advice. It does not prevent confirmation bias, of course.

Yes that is true, and it is all subject to bias for sure. I have never been one to buy into the super expensive cables. I am more a mid tier guy. 

A better way to think of this is that good power cables don't improve sound.  Bad power cables degrade sound.  an inadequate power cable won't support short (picosecond) bursts of high current needed for fast dynamics and sharp bass.

The way I see it, if you spend a bunch on cables it HAS to sound better right?
