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.

... So off with the $25 coaxial and on with the $500 one. The difference in sound? Not a cintella of audible difference ...
It would be a mistake to assume that the results you obtained with one simple experiment are universal.

An example would be a series-mode surge suppression/conditioner that doesn’t use Power Factor (energy reserve) technology. The result would be reduced dynamics and bass impact due to dynamic current-starving of a power amp.
"That’s nonsense."

Furman uses the term "Power Factor" while Audioquest calls it "Power Correction." In both cases, energy storage is provided by large capacitors that can satisfy the dynamic current demands of power amps. Without the caps, the very component (inductor) that limits the surge current also limits the dynamic current that is available to the amp. Simply put, an inductor opposes changes in current flow and that presents a problem for power amps.

I think you’re spending a little too much time reading manufacturer’s brochures and not enough time understanding what’s going on. Audioquest can use whatever marketing lingo it likes, but "Power Factor" is the accepted and proper term for describing the relative phase between voltage and current, which in residential environments is typically 1 or very, very close to it.

Yes, that’s what capacitors do.
Without the caps, the very component (inductor) that limits the surge current also limits the dynamic current that is available to the amp.
If you think all power conditioners rely on inductors that compromise PF, you’re mistaken. You're also mistaken if you isolate PF as the most critical factor in delivering full power.

The Puritan 156 was my 2nd choice. It is a very good unit. But I passed on it because it had (9000A) surge suppression chokes or the like and instead had an electrician install a Seimens FS140 with 140,000A protection at the breaker box.

I would look into PI Audio's UberBuss. It has independant outlets, a power factor correction of 1 and a non metal exterior box to eliminate Eddy currents and more. Each outlet handles 20A+( to Puritan's 15A). The UberBuss can actually output 40A+ spikes....It cost less than the Puritan and IMHO is a better power conditioner.

Get a Triode Wire Labs High Power Digital Ameican power cable with the $ you saved and you'll be in the best situation.

Look into the UberBuss before you buy.

You seem to be making some very broad assumptions which are simply wrong. I'm well acquainted with series-mode and parallel-mode surge suppressors/conditioners and their design differences.

You seem to have an argumentative nature. Is everything all right?
