Power cord choice?


Hoping to change (or upgrade) my current PC in use with my ARC CD3 Mk2. Currently I'm using a Locus Designs Polestar and setting a limit $600 max. I'd like to find a cord that can get more micro details from the ARC yet, I'd like to retain the smoothness but, try to open the sound stage and get a little more bottom in doing so. I listen to Alt rock (Sir Sly, The Killers, Gargage), rock, blues using Classe CAP 151 integrated and Apogee Slant 6s. I know this is subjective but, I'm also doing my best to work with my budget constraints and I'm not going to change if the improvement would just be slightly incremental. I'd like suggestions to consider, please.

Power cables as a tone control and music genre specific-? 

Good luck with that.

Better to just buy a few with a return policy, and you're just out shipping. Asking on a thread will just increase your A.N.
I have all ARC equipment (click on my user name to see my systems). I prefer Transparent interconnects and power cords. You want interconnects and power cords to do no tonal changes to the ARC signal. I have found Transparent best for that. I am not alone… it is a “known” synergistic association.

Shunyada has a good discussion of why the “last few feet shouldn’t matter argument” does not work. But logical arguments don’t really matter, when you change the PC and the sound dramatically changes… you just have to throw the argument out the window because it doesn’t explain reality. 
Sounds like a big waste of money.  I would add a power conditioner before I wasted $600 on a power cord.  
bigtwin, why are two opposing cylinders a good idea? Taking the heat?  It may be better to have one larger one, or instead four. Or watercooling is the only way. The Kool-Aid work's best with high percentage of Vodka. I celebrate that I can poop on your opinion, also. Seriously, there are MANY personal experiences of trusted, or respected members accounts here resulting in much "perceived" improvements in the addition of such upgrades. Your experience did not pan(head) out, vive la difference. 
@isochronism   Kudos to you sir for recognizing the reference of bigtwin.  So few do.  As I stated previously, your opinion is just as valid as mine.  I only state the facts of personal experience.  Upgrading cables has made little to no difference.  And clearly I am not alone in this camp any more that you are in yours.  We should all endeavor to persevere in the search for an improved Hi Fi experience.
