Audioquest NRG Z3 power cord

[Johnnydev]

Wow - such a difference in speaker cables. What is strange though is that normally higher ranked power cords should provide a better performance. Maybe they were not all on the same level of burn-in or something else?

No, all tried for several weeks/months. And checked after weeks by changing the cables.
This is in my situation, in another it can certainly turn out differently.

Audioquest, Garth Powell etc. have indicated with regard to the Z3 that the cables can only reach its full performence in the same place for a long time, at least for more then one week!
