Jamin, the 875 has plenty of maximum power capacity in its standard operating mode, as the S&V lab tests indicate, so you shouldn't be worrying about still more maximum capacity from bridging(incidentally, the S&V article correctly mentioned that the bridging was at 8 ohms; bridging can't change the impedance of a speaker or other load which is being driven). But no, if you did it, the M50s can handle brief bursts of maximum power in excess of the conservative number given in the Axiom specs. So again, you should worry about your ears more than your M50s.
