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.

I’ve always made my own; using 16/3 old-fashion style fabric covered cable, hospital grade plugs & locking IEC  connectors. While I’ll readily admit I can’t hear any differences between mine and the stock ones; mine definitely are a lot more attractive!  And the materials are quite reasonable in cost. 
Signal Projects power cables are relatively unknown but are very impressive in terms of performance. I just got their Atlantis power cable and I was actually very surprised how much tighter and detailed all genres sounded. Soundstage was also noticeably better.
Signal Projects also service a very wide price range with all of their different families. For your budget I would go with either the Monitor or the Lynx power cables.
I tried different PC, didn't here anything earth shattering. The most expensive being synergetics blue. I then tried audio quest tornado and monsoon. Kept the monsoons for my 3 Amplifier's. They fit the best in my Parasound amps. All other PC are audio quest paid for with points from Amazon. 
I would try an audio magic power cord they are incredible on source components.
You guys are all wrong. Watch this video from an electrical engineer/musician. It’s solves the battle
