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.

well then Ozzy you should try power cords from companies like Harmonic technology acoustic Zen or any other companies that use OCC single Crystal, audioquest charges an arm and a leg for it other companies use the same wire and much cheaper audioquest is ripping people off big time Harmonic technology Neotech and a few others have much more reasonable prices for the same OCC single crystal wire.

Can anyone here (or anywhere else for that matter) explain in a scientific way, how electrons traveling over, around, and through wiring of any type, change the properties of said wire to supposedly improve the sound?

 

Also, in more than 40 years of reading about stereo stuff, I've never heard of something sounding worse after the supposed break-in. Why is that?

@mrskeptic This video explained it IMO. Jump to about 11 minutes in to speed it along. At about 24:30 minutes in, he explains break in.

 

Mr Skeptic,  PS Audio does some great videos addressing this.  It is not snake oil. It is complex physics.   Happy trails!

If someone selling the item points out why it works then it isn't snake oil.  (just pointing a a common flaw in logic here). --Jerry
