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.

you’re better off spending your money on better components than you are wasting it on interconnects. I have $40,000 worth I have equipment all connected with AmazonXLR cords. It sounds amazing I have people over all the time that if they knew I used Amazon cards they wouldn’t believe it. This is not an ad for Amazon this is an argument against thousand dollar power cords add thousand dollar interconnects

For all of you guys out there who are smarter than I am with computers here’s a guy who shows you how to perform a null test With some software and computer. It would be interesting if somebody out there could do annual test on their computer between a normal cable and an expensive cable and let’s see if these guys are full of it or not
