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.

Forgot to add that I had a 60hz buzz before that I really couldnt hear with music playing. Gone as soon as I hooked up the Triode Wire Labs cord.
I'll be hooking up my Triode Wire Lab HP Dig American to my Rowland mono amp for my center speaker soon.
Picking up my TWL 7 PC today. It's going on my integrated and I'm going to try the loaner TWL 10 on my phono pre. Also am demoing an Analysis Plus Power Oval 2 that I will rotate in. Should be an interesting few days. We have some friends visiting as well so listening time will be limited till Tuesday.
Make your own get good Furutech Copper good connectors
