I own a 275 mk IV paired with B&W 804S and love it. The speakers' aluminum tweeter are considered bright by some people, and I find the combination with tubes to be very good. Your Focals were on my speakers short list too, but wasn't able to audition and decided for the 804.
BTW, are you positive the MC41 is REALLY balanced? Some McIntosh components have XLR connectors but aren't really balanced by design. Not that this should be a deal breaker (eg; my pre only has RCAs), but I guess you should be aware of what you are buying.
