I don't have 802D, but 804S. I biwire. Does it make a difference? Probably not.
I drive the speakers with one MC275 and love the sound. I am finishing a couple of class D Hypex monoblocks to drive the woofers. I plan to get rid of the passive crossover between woofers and midrange and apply an active crossover there, keeping the tweeter-to-midrange passive crossover driven by the 275. My understanding is that active multi-amping (as in active crossovers) is the real deal. FWIW my subwoofers run below 80Hz while the MC275 takes it from there and up.
