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.

It is not only the crystal structure that is changing with current. The diode effect has influence on the directivity of the cord, the saturation of the diëlektricum acts as an capacitor on the time domain and varies after burn-in. And then there are easier measurable things like the EMIRFI contribution/blocking attributes of the cord (on the surrounding cords for example) next to L,C,R measurements.

I can get the point of abiding this is true, for say, a speaker cable. But what sorts of time domain (smearing?) is in a 60Hz power cable that makes it into the power amp?

This thread reads is like a group therapy session. And it is getting apparent that out crowd has not experienced the effect.

jakesnak,

Wow, your home sounds great! My wife has always wanted a log cabin home. So, I bought a barn...but that’s another story.

While I am skeptical, I would be very interested if it did work, and also the theory of how.

But I think that you are correct in that what people say will not likely move the skeptics.
It would likely take a measurement showing some difference… or some A/B deal where at least one person can identify whether it has the power cable or not, say 10 times of of 12.

@ozzy 
None the less, I’m happy it is working for you sir.
