I can't answer your question specifically, but related to many suggestions already given, I am using Acoustic Zen Absolute speaker cables yet Silver Dart power cords. No, I don't have a good answer why it ended up like that, but I am in no hurry to make any changes based on the sound quality I am getting. I imagine the Silver Dart speaker cables and IC's sound just as good, but I haven't compared.
Question to @ozzy though, I am seeing a large number of used AQ dragon's; not just here but in other classifieds as well- I wonder if all are legit/non-counterfeit? At this price level there must be plenty of incentive for knockoffs to flood the market. Have you/anyone else heard of anyone getting a counterfeit?
