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.

I've had my whole house rewired with pure 10 awg copper, but the power from the grid just doesn't do it for me, so I've gone green and added a wind mill and enough Solar Cells to generate my own, clean, green power. But since it rains a lot in Houston, and every once in a while the winds from the Gulf stop I also installed an GE LM6000 gas turbine generator. It's a bit loud, and uses a lot natural gas, but I get to sell my excess generation (close to 100 MW/h) to the grid for a nice tidy profit.

Although it's hard to hear the music over the roar of the turbine, and my neighbors are a bit annoyed, I think I finally have solved my power problem.
If that new power cord doesn't work,these folks might be interested in your GE.You Tube>>>[http://www.youtube.com/watch?v=5jN0bqL9cM0]
One of these might help keep the neighbors happy if you keep it.[http://www.airport-technology.com/contractors/groundequipment/blast-deflectors/blast-deflectors4.html]
HiFiTime that great, and the best part is that between the 110 MW/h turbine genarator, and the new blast deflection soundproofing you have so kindly suggested, I'm probably only going to be in about $22 million. That's still less than a lot of the Hogwarts graduates here pay for their power cables on their $20,000 worth of gear.
I wish they could understand a power cord can't condition. It's still the same.Dirty power into the cord,dirty power out of it.I wonder if all the engineers have super cords on their test equipment.
