The C 275BEE boasts many upgrades and refinements taken directly from the highly acclaimed NAD Masters Series M3 Amplifier. These include application of Bjorn Erik Edvardsen’s innovative and patented Distortion Canceling Circuit in the output stage and BEE Clamp in the power supply. An improved tone control circuit and revised PCB layout has reduced distortion and noise to unprecedented levels. Taken together, these improvements mark a sharp upturn in performance that simply must be heard, to be fully appreciated.
