Power Cables which take the soundstage back

Hello,
I have almost always focused on ICs and Spk Cables...but I always knew that Power chords also make a good difference. This is the first time I am venturing seriously into power chords. I am not looking for anything fancy. Primarily I see power chords should be doing the following:

a) Clean up the background noise (because of better shielding etc) which a stock chord would not be doing a good job at.

b) Provide good current capabilities which enables to make music denser, tones get more body and especially bass gets meatier and tighter (the last one normally happens more often)

These are primarily two things I am looking at.
I have tried some power chords in the near past and I have observed one common pattern:

1. Power chords which tighten up the bass (in comparison to stock chords) also bring the images a bit forward.

2. Some Power chords do a good job of taking the soundstage further back...I dont know how and why but I have seen it happening. Some of them end up presenting a bit loose bass in the process (only some of them)

So, for me at this point, a power chord which can take the soundstage back (without introducing anomalies like loose bass) would be a wonderful addition. Thats a very critical requirement for me. I am sure you guys would have experienced power chords which do such things. I am not intending to shell out more than $200 (new or used) at this point. Kindly suggest.
