High priced power cable what about the romex

I have a question that I tried to post before but for some reason it was flagged by the moderators.

I have nice looking power cable some signal, some MIT, some home made, and they look like they should do a great job, could even run a small town

My question is if you run romex from the fuse box to your high priced outlet, and then plug in your high priced powercable, how will this improve the path from the fuse box to the outlet? And if it doesnt why not just run the same romex to your HiFi.
How does a better grade power cable improve the path from the main grid.
I have heard this again and again "Your system is as good as its weakest link" So isnt the romex one of those weak
links?

I am sure there is a good responce to this and I am not trying to be negitive in regards to high priced power cords but what am I missing?

Your power cable can act as an antenna that picks up noise from magnetic fields and radio interference which is all around. If the power cord is shielded properly, then it will minimize the introduction of noise from these EMI/RF fields.

It does absolutely nothing as far as improving "power flow" or current draw or anything to do with electric power. The improvements you hear with power cords are the reduction of the noise floor from the EMI/RF noise rejection - which is what may happen if you "run the Romex to your hifi".

Some cheap cords can do just as good a job as the ones that go for a grand a foot with respect to noise rejection. Keep an open ear before you spend the big bucks needlessly.

percieived quality of the sound
So it is all just a perception?
OK now I understand that Romex = ground noise and all those oter gremlins, but if all we need to do is shield the copper stands then why do people pay an exuberant amount of money for shielded copper strands.
I am sorry that I don’t get it but it just seems totally idiotic.
I understand everything is relative hell if I was Trump I would buy those Wilson’s and that $10,000 IC but even if I did I want to know why is it $10,000 what makes it different than say Franks “Signal Cable” Power Cord (Which is what I use)
