@ozzy , I’m at 240 hours on the three AQ Dragon power cords and they are really opening up starting today. I actually hung on to one of the fully burned in demo Dragon cords for a bit longer. I tried replacing one of my new cords with the fully burned in demo cord, the one feeding my Tambaqui DAC. Sure enough, the fully burned in demo cord made my system sound even less constrained, through the entire frequency band. So even at 240 hours I think my cords have a ways to go.
I read a pro review of the Dragons where they say AQ says that it takes two weeks “to form the dialectric”, and two more weeks for it to fully improve. And yeah I know many give AQ flak for stuff that may not be absolutely grounded in science, with their little battery packs attached to the cords. All I know is the cords sound great and they are getting better, as I can easily hear comparing the broken in cord with the new ones. Haven’t done a blind test yet but I’m sure I could easily tell the difference. But not for long as my new cables catch up.
