Does Power Cord Require Burn-In To Sound Good?


I recently bought a new power cord but there isn’t much difference in sound quality between this new cord and the previous Wireworld Elektra 7 which it replaces. The cords are used on the DAC.

Any ideas if the cord needs to burn in to open up and sound better? It currently has about 5 hours on it and I think I prefer the sound quality of the previous cord which costs 10 times cheaper.

Any thoughts appreciated.

I am pretty certain that the person who wrote this has no formal education, physics , engineering or otherwise related but is obviously making a failed attempt to insult those that do.

    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.      

" So they can make one model for all markets."

- No, don't buy it. Different voltages in different countries can't be remedied by power cords only. 
@audio2design- I’m absolutely certain (experientially); you’re absolutely wrong.        Yours is simply another uninformed, Naysayer Doctrine adherent’s assumption.        Now: deny the possibilities, offered by the facts presented.

Nice to compare the Acrolink to a WW Silver Electra7 PC.
Keep me posted as you massage those newer PC into your system.

Happy Listening!
