Power cord choice?

@thyname  I use a Furman P2400 IT conditioner, Hegel 590 integrated Amp, Acoustic Zen Crescendo Mark II (also Goldenear Triton Reference), Thorens turntable with MC cartridge, Vertere phono preamp XLO Signature 3 speaker cables.  Quality interconnects.  What I would call a decent system that scratches the surface of true high fidelity.  My first PC upgrade from the stock cable was from Gutwire.  Then I moved to the current Furutech.  Have no plans to try more cables in the future.  I agree that switching from a really cheap cable, that starves your amp of the current it needs, to a decent 12 gauge wire in the $100 - $300 range would probably benefit your system.  If nothing else, getting rid of the hum from an underpowered amp.  But past that I believe in the law of diminishing returns.  Reading about a PC where the manufacturer uses six9 copper, I get it, and then cryogenically freezes the wire?  Now I understand that copper may have different/better transmission properties at extremely low temps, but my air conditioner just doesn't get my sound room down to -175 degrees.  And I question if anys gains realized at those temps doesn't disappear when the wire returns to normal room temp?  And riddle me this one.  The finest made, $10,000 PC should claim to pass the current through it and add nothing to it?  I haven't read anywhere that the PC has filtering properties?  If this is the case, then any noise or interference that is inherent in the home power source should get passed right through the PC?  Common sense tells me to use a decent cable to deliver power to the conditioner.  My personal experience, and let me stress it's my experience, that upgrading the PC has not enhanced what comes out of my speakers.  Heck, I want to be a believer, I want to hear the magic, but that simply has not been the case.  If the holy grail of cables may in fact be out there, but my money will be spent on more tangible results.   

The Zavfino PC mentioned by Lalitk is Outstanding!

bigtwin, I agree with you fully. Btw, I own a twin Ducati, never ridden, but look's nice on display. Harley's are legendary! Good to have you aboard here. 👍

Better to just buy a few with a return policy, and you're just out shipping.

Big +1.  I’d recommend trying Triode Wire Labs, Underwood/Core Power, Audio Envy, Cullen, Raven, and the Zavfino mentioned above by @lalitk also looks very intriguing.  Best of luck. 

Big Twin: just curious, what power cords did you try, and in what equipment? Thank you 

@isochronism   Kudos to you sir for recognizing the reference of bigtwin.  So few do.  As I stated previously, your opinion is just as valid as mine.  I only state the facts of personal experience.  Upgrading cables has made little to no difference.  And clearly I am not alone in this camp any more that you are in yours.  We should all endeavor to persevere in the search for an improved Hi Fi experience.   

bigtwin, why are two opposing cylinders a good idea? Taking the heat?  It may be better to have one larger one, or instead four. Or watercooling is the only way. The Kool-Aid work's best with high percentage of Vodka. I celebrate that I can poop on your opinion, also. Seriously, there are MANY personal experiences of trusted, or respected members accounts here resulting in much "perceived" improvements in the addition of such upgrades. Your experience did not pan(head) out, vive la difference. 

Sounds like a big waste of money.  I would add a power conditioner before I wasted $600 on a power cord.  

I have all ARC equipment (click on my user name to see my systems). I prefer Transparent interconnects and power cords. You want interconnects and power cords to do no tonal changes to the ARC signal. I have found Transparent best for that. I am not alone… it is a “known” synergistic association.

Shunyada has a good discussion of why the “last few feet shouldn’t matter argument” does not work. But logical arguments don’t really matter, when you change the PC and the sound dramatically changes… you just have to throw the argument out the window because it doesn’t explain reality. 

Power cables as a tone control and music genre specific-? 

Good luck with that.

Better to just buy a few with a return policy, and you're just out shipping. Asking on a thread will just increase your A.N.

I'm sure I'll take some heat for this post but I'll say it anyway.  The power to your equipment travels miles from the source to your home.  Through your main panel and walls to the final outlet.  Your amp and/or power conditioners are designed to take the raw power, filter it, clean it, do all the other magic and then send the signal to your speakers.  How do we believe a 3 foot piece of cable, from the wall socket to the amp is going to change the sound coming out of the speakers?  I've been down this rabbit hole.  From the stock cable the amp came with, to a $300 dollar upgrade, to a $1500 Furutech with Carbon Fiber connectors.  Can hear no difference in the music between the three.  I believe confirmation bias accounts for the difference some people hear.  I believe it sounds different, therefore it sounds different.  Kraft must sponsor a lot of the advertising as this hobby drinks a lot of Kool-Aid.  This may only be my opinion, but that's the beauty of a discussion.  My opinion is just as valid as the next.  

Consider this power cord at a price that belies its high performance and built quality.
