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.

Sounds like an admonishment from a priest. This guy is off the deep end, for sure. His is the type of personality that gets profiled on cold case t.v. shows.

what is the current Power Cord in comparison to the WW Electra 7?
Yes, a new cord requires 200 hours of break/burn-in, unless done so at the factory.

Happy Listening!
Jafant, it's an Acrolink Mexcel 8N-PC8100 Performante. Thanks for all responses though I didn't expect the animosity displayed on this thread. Anyway for closure just to update that I'll be keeping the cord after all as the sound has improved approaching 50 hours and it's now sounding a lot better. It really sounded quite horrible out of the box (below 5 hours).
