I listened to K-01 extensively at RMAF 2011... While it is rather difficult for me to contrast K-01 with my own X-01 Limited, without having both in the same system, K-01 was A/B/C/Ded against several lower end Esoteric players in the suite, with audible results commensurate with a good fraction of the respective price differences.
The benefit of controlling K-01 through a G-0Rb clock was not at all a subtle affair... The audible result was rather obvious to me, as well as to all listeners I queried on the subject.
I left RMAF intrigued enough that I intend to audition K-01 in my own system one way or another before too long.
Harv, it was absolutely fabulous finally meeting you!
