I have B&W 804S with my MC275. Very good match, but I often wonder if there is a better match for the 275. One thing I do know, though, is the N802 in your short list would need more power. Maybe 2 MC275 could drive them well, but only one will for sure be too little power.
FWIW, I did audition a pair of ML (can't remember model) and thought my 804S sounded better.
