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.

Acrolink/Acrotec is widely underappreciated.

I have Acrolink IC's from long ago, and try as I might, I've never found another brand or model that sounds better than them

Sadly never had one of their PCs.

It's a pity the brand isn't more widely available in the US.
Did you remember to tape; silver duct tape, not scotch tape; the power crystals to the top of plugs? Remember the tapered ends of the crystals must be facing true north, not magnetic north. If you can get some of those power crystals from Indonesia, the ones that have passed through a flying monkey, well those definitely sound the warmest as the molecular make-up of the stone shave been warmed by the animal.
Thanks for the laugh today, you guys are a hoot, I needed it.-E
Really hate to tell u this I have several wireworld power cords sitting around because they really don’t do much to improve the sound of my systems
their interconnects and speaker cables are much better than their cords
in the pass I have replaced 400$ wireworld cords with 99$ Shunyata venom and the difference was more than noticeable.
Power cords do need burn in for sure
now I have moved from venoms to more expensive shunyata cords and they just keep getting better! 
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.
