Lak-
I can offer you some intel based on the things I have read about Stage III IC's. Oddly enough, if you have had any opportunity to audition their power cords (PC) then you know the aspects that are being raved in this thread.
Oddly enough, again, Stage III IC's are nowhere near as good as the companies' PC. Search the webzines like 6 moons & dagogo where you will find the reviewer(s) received both PC + IC(s) for demo/eval- none kept the IC(s)...strange?
