Thanks for sharing the good write up.
I too enjoy my MF A5 Int immensely with my B&W CDM 1NTs and what you have described parallels the synergy I hear with my rig.
I know the A5 is the much jr offering compared to the Kw500...if I could only win the lottery
I've also read that B&Ws seem to match better with SS amplification, but will admit that was something I read on the internet....
