Power Cable Break In - Such a Change!


I installed a new AudioQuest Dragon Source power cord from my Lumin X1 to my Niagara 7000. The power cord from the wall to the Niagara 7000 is also a Dragon but the High Current version. I bought that cord used.

So, when I first started using the new power cord everything sounded great. However, after a couple of days I started hearing a strident sound. Especially in the upper mid/ treble region. The bass was also constricted. I started blaming the sound change on another piece of equipment that was installed concurrently.

Now, I was under the impression that the Dragon power cord with its DBS system required no break in. But I did inquire about it to AudioQuest who responded that it would still need about 150 hours to break in. It's been close to that now and sure enough yesterday I started hearing the glorious sound that I heard from day one with the power cord only perhaps better.

I must say the difference during break in and now is quite remarkable, I don't remember any other power cord going through this amount of dramatic change.

     OH, and: it takes some time for the dielectric to form, take a charge, polarize, or however one chooses to define the process, when a dielectric is subjected to electromagnetic waves, which affects the Poynting vectors, measurably/predictably.

              The lower the material’s dielectric constant: the longer that takes.

                                               PC burn-in?    Maybe?

Perhaps there is no current viable device that will measure our sonic preference? I mean all we have is Ohms law. If you're hearing and your system is transparent enough, most people will be able to detect the differences. Why such a denier? Try it.

I might.

At 60Hz, that is a huge time.

I can abide that speaker cable playing the 1kHz or 10-20 kHz can do all that, but 60Hz is very low.  

Maybe being on 50Hz makes it less of a problem?

...you have just entered the land of confirmation bias ...

Which inevitably leads to the sea of cognitive dissonance.

 

Is there any other hobby that makes more wildly unprovable claims than this one?

Yes. Electric guitars and tonewood. That myth has been busted many times, but is still going strong.

I’m not going to say there is no such thing as "burn in" but there is no physics that says a copper wire will change with low levels of current flowing through it for 300 hours. Hot things, such as tubes, will certainly change. Anything that glows is undergoing metalurgical changes that hopefully will mostly stabilize, hopefully for a long period of time.

But if you were a seller and had a buyer thinking about returning an item, any item, even a rock or a nail that he just bought, if you could convince him that it will get better if he sits with it for 300 hours, that will greatly reduce the risk that he will return it.

And "audiophiles" have pretty much posted all over the internet that they will believe the "burn in" theory for any and all components.

Make your own decisions but I will suggest that you don’t believe eveything you see on the internet. Make sure you read the last line:

Ozzy,

 

any system changes headed your way this year?  You run a very interesting combination of Cables/Cords my Audiophile friend.

 

Happy Listening!
