ive owned & ran the mc2102 in bridged mono & it sounded great,everything doubles in bridged mono,like wattage & distortion but doubling 0.005% distortion isnt going to give you any noticable difference in sound quality.
IMO amps that give up the goat when ran in bridged mono are poorly designed to begin with,the mc2102 is perfect for running in bridged mono with no ill affects in sound or performance.
