Power cord choice?

@raysmtb1  Thanks for that video link.  I actually watched the entire 30 minutes.  Although it pertained to audio signals being passed through various wires, I assume the results can be attached to PCs as well.  I recently took the plunge and bought a $500 custom coaxial cable.  In part based on all the postings on this site telling me there will be a big difference in sound, and partly on a long comparison of cables in Absolute Sound magazine.  The reviewer tested 50+ cables and made his top three recommendations.  In the review of the cable I choose, he claimed "the music danced like fire from the speakers".  Well I ask you, who doesn't want that kind of result when you change out a cable.  So off with the $25 coaxial and on with the $500 one.  The difference in sound?  Not a cintella of audible difference.  Switched the cables back and forth.  Identical results.  And not just to me.  To my wife and a few friends that have braved Covid to come over and listen.  I'm still using the expensive cable because maybe the fire is there and I just need time to hear it.  Sure that's it.  I'll hear it later.  It's only been a couple of months.  Maybe the cables not burned in yet. Yeah, that's the ticket.

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.
