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.

This formula should help;
The perceived improvement created by a piece of wire introduced into an audio system is directly proportional to the price you paid for it divided by how embarrassed you are about admitting how much you paid for it squared by the volume of space in your budget where money used to be.
Typical argument from someone who hasn't done the experiment but knows that it can't have an effect. And always brings up a cost. Don't understand why it bothers you so much.
What did you expect, of course power cords do NOT make a difference to the sound, unless you change all the wires from the actual generating plant to your system. Even then, you will hardly hear the difference, unless you are a super being, very likely from another planet, and a walking wheatstone bridge who can tell the difference between 0.001 ohm and 0.0011 ohms.
Nope, no need to do all that. just from the wall to your component. Try it you'll like it. Even though you know you won't.
