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 definitely noticed the burn in phenomena with my audio quest power cables: monsoon and blizzard

Sometimes they sound worse before they get better. Do what MC sez. Or be sorry for the massive outlay. I think you would have been better served putting the $$ into a fuse for your DAC. If you haven't already that is your constricter. A 2" pipe is ineffectual going into a 1/2" valve

I don’t know what the return policy is, but assuming it’s 30 days, leave it in your system for 2 weeks, listen to a lot of your favorite music and then switch back. You should have a very good idea of whether you’ve improved the sound or not after that. But definitely give it a chance.  And remember, it's not about which cord is "better".  It's about which cord you prefer sonically in your system.  I had a Wireworld Aurora in my system for a while, but I found my old Black Mountain cord sounded better, so I packed up the Wireworld for another day.
