Help selecting a power cord.

Hello,
As many stated above power is the single most important factor behind a good performance out of your A/V system. For me what worked best in this regard are
1. Two dedicated circuits with 10 AWG Romex cable
2. Furutech Receptacle GTX-D NCF(R) kit- the receptacle, aluminium side bracket and faceplate
I connect all source components to one receptacle and power amps to the other receptacle. 
The level of performance I get out of the Furutech receptacles is way better than any power conditioner/isolation product (Audioquest Niagra, Shuniyata Denali, Einstein, etc) that I tried in my system.
Now coming to the power cable, for my system, it is always the source components where I find a better power cable almost always enhances the system performance.
I was using Nordost Frey-2 power cable for a long time. However I have replaced it by a relatively low profile brand Audio Sensibility based in Canada. I am using their signature power cable and I couldn't be happier. Their signature line of cables is so good at least in my system that I replaced most of the Nordost Frey-2 cables. In my system I have no hesitation to say that they beat Nordost Frey-2 hands down.
It is definitely worth a try if you are looking for a good cable at a moderate cost.
Thanks.

What a potentially confusing collection of responses!

You feeling overwhelmed ninja12?

I don't belive you ever stated your budget.
That would've helped. 

Power conditioning might or might not be worth the investment. 
Where I live, the power is very clean-- I tried a PS Audio regenerator
in my system and could hear no difference, nor could the dealer. 
YMMV.

Your initial post discussed starting with one power cord-- perhaps you ought to stick with that idea for now, before diving into the "Power Product Vortex". 

You've been given some suggestions for power cables, at a variety of price-points. 

My experience concurs with those who suggest you start by upgrading the power cord to your amp/integrated. Order from a company that will give you a trial period and refund, should you elect to return the cord.
What have you got to lose? (OK... shipping costs, but that typically doesn't add up to much).

Unfortunately, the Audiobacon cable review as all other suggestions is only an opinion which many will disagree with.

One has to begin somewhere. One can research the opinions of others or not-- utilize them or not. If one knows what one's priorities are, in terms of SQ, then reviews can be helpful as a starting point.  I never claimed others' opinions were a magic bullet. I would've thought that was self-evident!  

Unless, of course, you've discovered a purely objective means of determining how a given cable will sound in my system, in my room, to my ears/brain. . . 

There's a bacon cable? Wait- let me guess: It's sizzling.
