power cables' effect on power conditioner?

Is it going through the wall? in the wall? Or out and easy to see the whole length? 
If out. perhaps use some cladding that is used to hide wiring? Covering a steel flexable cable with some neat cladding would be a big WAF.If it is inside the wall...    I think if you start with it coming out of a code box at the wall, with an added code allowed fixture to allow the cable to exit the wall intact. Like those metal oblong covered L shaped lozenge seen in commercial installs. 
With a pipe or the cladding for hiding wires from it toward the Niagra.. (maybe painted to be less noticeable?) 
Then right by the Niagra the end of the pipe with a surrounding plastic or rubber plug letting the actual cord stick out to the IEC plug...
I would think it would be a passable looking item.
I run a dual quad set of 12 gauge wires with a pair of ground wrapped in,  Wrapped in blue teflon tape up over the ceiling to the living room and back down...(about 36 feet long)  In my apartment. The folks in charge of the building have never complained. Though they have seen it many times. The one outlet in the kitchen is a 20 amp alone on a circuit breaker. and I wanted to use that.

Any power cord cord will impact the sound of any gear you plugged them into. It’s how they impact the gears power supply and that is an unknown which is why you try before you buy.

@emailists , it was my understanding that steel shielded cable should not be used in audio applications. The link you provided states the use of this cable is for...

"Branch circuit and feeder wiring for computers, programmable controllers, electronic discharge lighting, office machines and other electronic equipment that introduce additive harmonic currents from non-linear switching loads"

Maybe you can enlighten me as to why this cable would be superior to 10 gauge Romex. 
I thought BX type cable and metal conduit should not be used from circuit panel to audio system.

I found mention of that steel shielded ac cable on another audio site but no one had actually used it.  They also have already aluminum cased version.  Would that be better?

In My application the cable will be in wall for for A foot or two from the breaker box then run on Wall or along the floor in mostly hidden areas.   That's why I thought steel encased cable would be advantagous.  I also just read about  VH audio Cryo treated romex.    Not sure which direction to go - I'd like to hear more about why steel or conduit should not be used.  

@emailists , I'm not an electrician or an EE. I think the issue with a steel shield or steel conduit is that it should never
touch the ground wire of the dedicated line or become grounded to the destination. eg, the circuit panel ground buss or a steel receptacle box.

If you are not consulting with an electrician, you could start a new thread about your dedicated line. Many  experts on the forum will respond.
