Does Power Cord Require Burn-In To Sound Good?

" There isn’t any physical process that causes any modifications to the marcroscopic or microscopic structure of a cable during what you call ’burn-in’ .Cables burn-in does not exist."

-- Ok, we finally got the word, no sense in talking, debating or experimenting anymore. I wonder what other absolutes we might be enlightened to, can’t wait.

It could be that you just didn’t spend enough money for the placebo effect to kick in. 

There is no sound difference from power cords other than what you imagine you are hearing. Signal cords yes due to capacitance. Power conditioners help isolate noise but most pwer supplies do that anyway.

Invest your money on better amps or speakers or DACs. Buy a good quality 12 AWG IEC power cord from Amazon for $12.

PC in no way is going to improve anything over the stock cords. Freaking ridiculous to think otherwise. But knock yourself out!!

Anyone, genuinely interested in some of the parameters/considerations, possibly governing the faithful propagation of our signals/voltages, as regards cabling and components, should study the following.      Having no formal (or other, it seems) education in Physics; the typical Naysayer Doctrine adherents, will undoubtedly offer their ubiquitous, Newtonian (1800’s Electrical Theory), ceremonial whines, for your Communion and salvation.               It’s common knowledge, to anyone with a background in the Physics of dielectrics, that the better a dielectric (ie: Teflon, polypropylene, etc), the longer it takes to polarize, with smaller signals/voltages.       https://en.wikipedia.org/wiki/Dielectric      and: https://en.wikipedia.org/wiki/Speed_of_electricity#:~:text=Speed%20of%20electromagnetic%20waves%20in...                  Even the Wiki-scientists are more knowledgeable, regarding modern Electrical Theory (not to mention QED), than the Naysayers.
