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.

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?

Although I do agree with this above statement.

And I also agree with our own beloved @geoffkait who stated:

’Let me explain. Electronic (Electrical) engineers don’t get any courses in Materials Science, Engineering Science and Strength of Materials as do Aerospace Engineers and he obviously has zero experience in cryogenics whereas I have 20 years of experience.’

Love the guy.

     As ANYONE, that has the slightest inkling of how the process works, knows:  "...when science doesn't have an *ANSWER," it comes up with a, "THEORY".

              *ie: To that other 96% of this universe, Science can't explain

     BUT: the process ALWAYS starts with an OBSERVATION made by someone with an interest in what's going on (in this case: differences in an acoustic/musical presentation).

     For a lot of us, that enjoy music and the acoustic in which it was recorded, reproduced as realistically as currently possible: HOW that works, with whatever component chosen (be it a new room treatment, preamp, amp, speaker, cable, stand, fuse, etc), isn't as important as THAT it works, to THEIR EARS.

     But then: I imagine I'm not alone in researching how electricity acts (or: MIGHT act), when encountering various circuit configurations, dielectrics and metals (according to post 1800s THEORIES and MEASUREMENTS that are easily available, to the honest fact seeker, as I've mentioned), before choosing with which component to listen/experience/experiment.  

     Gotta wonder: how many music lovers, that own a marginally expensive system, have ever studied Acoustics and can readily quote the Sabine equation (doesn't get more basic), or: ever bothered to ACTUALLY measure a room, themselves, before treating it?.

                                PERHAPS: that should be outlawed?

And with all due respect, when you suggest science can't do something, after being trained in the filed, WTF do you believe in when science doesn't have an answer,  witchcraft?

I'm happy your ears adjusted to the sound. Errr..... I mean the cable got broken in.

Very Interesting Topic. I have 2 Dragon HC, (1 meter) my Outlets Are Furutech NFC Rhodium. My amp is Gryphon Mephisto Stereo, which require 2 power cables. I'm not digging these Cables with the Mephisto. Perhaps because the Mephisto is the most transparent, amp I have ever heard? I don't know? Is it the Rhodium with the pure silver? Been using Furutech with their top of the line connectors, with S032N wire. I'm used to the silky-ness the Furutech provide. PM me if anyone needs more info on the cables...
