Don't know much about Kimber kable. But I am using the older version MIT 750 Shortgun biwired with my Nautilus 803 with great result. List price was somewhere around $1200 but you can find it used for about $400-500.
Well I just sold off my bi-wire Kimber 8tc wire, & went w/ Harmonic Technology Pro-9 bi-wire for my B&W's.
I was startled just the other night, as I'm hearing details that I didn't hear on Cd's with the Kimbers. The Pro-9's signal path is amazing, the brightness of the metal tweeter has been totally toned down, & the low end is more pronounced.
I did size down my length from 15' to 12' w/ the 9's yet, going from Kimber to Harmonic Tech. was like hearing a whole new speaker. I did scrap the whole Kimber Hero interconnect trail & upgrade to HT's Pro-silway II's.
I haven't used any MIT cables since the early 90's, yet I can't remember ever getting excited over any I ever heard.
IMO that's just my two cents.
