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.

Oh god, here we go with oldhvymec’s verbal vomitus and rhetorical mania again. He loves to entertain himself with prose only decipherable to himself. Regards

Yep, aside from real science and the principals of physics, cable burn in is a thing just like saturation is a thing. Auditory hallucinations can be obtained for the price of a coat hanger.

Please...

There's a serious issue here that few even want to address...what about cables that sound better BEFORE they burn-in. What then? Huh? HUH?? You just spent $5400 on a big ol' power cable and it just gets worse every day...cellos lose their cellness, death metal starts to sound perky and upbeat...it all just goes downhill...at that point you really have to have a stash of new cables and learn what rhymes with "Cardas."
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.

At least you have a working theory, not a very good one but ONE non the less.

If you can’t hear the difference, guess what, you can’t. I can’t talk you into it...That is the true QUESTION of this thread. Can the OP justify 10X for a PC that the SQ is not there OUT OF THE BOX...

Of course, they sound different...No one said better, different...

You need to save your money, you hear no difference.. Less expensive for sure...BUT don’t start spoutin’ YOU CAN’T, with some .000X anything... Crack me up... You can’t others can.

Isn’t it good when someone hears INCOMING, even if you can't... BTW  I don't follow blind people either, ask directions maybe. BUT follow, NO....

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.
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.
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.
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.
It could also be, that the very air in the room, requires a burn in period. Both to clearly transmit Bluetooth if you are using it. And also, importantly, to transmit the sound from the speakers to your ears.
No hobo, stats and specs are only that. For one to decide if any cable is an improvement, one needs to listen to it long term to decide, In high-end audio, everything makes a difference, good or bad. One just has to have the time and patience to make that determination. If you are convinced that is not possible, so be it, however it is not the last word.
Roberjerman is the only poster so far who has contributed anything remotely useful to this question. You guys really need to study some basic physics, along with ohms law and a chart on wire gauge and it's resistance rating per 1000 feet. Then measure the length of a typical AC cord supplied with most audio gear.
Hi, i think if you don't hear any good things from this, it's either because it doesn't match the unit's sound character (and maybe technical aspects), or because, you have already reached the maximum possible improvement a power cord can give to the unit, already with the previous cord! 
you will never get agreement here...use it a few weeks and you will know...
@ryder Welcome to the world of audiophile hyperbole, where even the direction in which a fuse is inserted in its holder can make the proverbial "night and day" difference.
Honestly, the more reviews and posts that you read before actually experiencing an A/B contrast with your own ears, the more disappointed you are going to be by the often underwhelming nature of the result of swopping B for A.
There *are* big differences in this pursuit, typically between two quite different speakers or two quite different amps.  There are plenty of other differences too, but they're on a spectrum from modest to small to minimal to barely perceptible.
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. 
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 definitely noticed the burn in phenomena with my audio quest power cables: monsoon and blizzard
Flat Earth Science at best! "The capacity of Humans for self-delusion is apparently unlimited" - Mr.Spock the Vulcan
Some PC's do need more time to burn in but improvements in certain areas would be audible, if none, especially for low powered dacs, then they will not sound much better when they break in.

Hate to tell you, if it doesn't sound good right out of the box send it back. Yes burn-in is real. But it won't turn a sow's ear into a silk purse. What it will do, if the cable is any good then it will sound terrific right out of the box, and then improve a lot as it burns in. If it sounds worse than what you have, at 10X the price, send it back. Do not wait. Do not listen to any cockamamie stories. Just send it back.
Currently there’s a minor difference in sound quality between the new and old cord but I cannot say which sound I actually prefer at this point of time. Doesn’t seem to be a very positive outcome at the moment..
Thanks for the responses. I'm seriously hoping for good things to come from this new cord as it's a pretty heavy investment for me. I hope this burn-in thing with cables is something that works ie. noticeably if not drastically improved sound after the whole burning in is complete.

Get a power conditioner if you are having issues. I kind of feel the power cord thing is a shame, unless you’re powering some real serious pull.
