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.

How does one go about doing that? 
Here’s the actual text of the private e-mail.   I’ll take bets on who it is (no real mystery here). This followed merciless attacks on me (because of my different opinion) in prior posts in a separate thread by this dude that were apparently removed:

“Shut up and learn some manners. I'm gonna ask you once politely in private.. I know who you are....

Just log back on under your real name, and act like a human, we'll get along just fine...

Regard..”

I have no idea what he’s talking about.  I have one account and post as myself. You can read the thread itself for further psychotic babble in this same vein that follows another post of mine he apparently also found a way to have deleted.

looks like this goofy thread is getting the 'attention and participation' it deserves... out...
Your name will not be spoken, you will be publicly shunned, you will apologize to all openly and publicly. You and your views and writing will be stricken from the record of the publics mind, they will view it with distain.

You will always be seen for what you are, there will be NO quarter given.

What you produce, is what you will consume.  
You will live and be seen by your works.  
And this sick, twisted crap is allowed to stand?  Moderator, moderator...?
