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.

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.   
Big Twin: just curious, what power cords did you try, and in what equipment? Thank you 
Better to just buy a few with a return policy, and you're just out shipping.
Big +1.  I’d recommend trying Triode Wire Labs, Underwood/Core Power, Audio Envy, Cullen, Raven, and the Zavfino mentioned above by @lalitk also looks very intriguing.  Best of luck.
