I've had Canare 4S11 through BJC for more than, gosh, 8 years maybe? They've been in and out of the system depending on preference or just to change things up. On my system, they present a little thicker in the midrange, but have just as smooth highs as the Cardas 101 through AA - both non-fatiguing. Imaging may be a little bit better on Cardas. Like all things, system dependent.
