M2 Direct Digital Amplifier

The NAD M2 Direct Digital Amplifier represents a new level of amplifier performance. Combining the ultra low distortion and noise levels of the finest linear Class A and Class AB amplifiers with the efficiency and streamlined signal path of the digital amplifier, the M2 is the first implementation of a new amplifier technology called Direct Digital Feedback. Co-developed with UK based Diodes Zetex Semiconductor, and using a unique implementation of their patented DDFA architecture, the M2 redefines what is possible with digital amplifier technology.

The M2 Direct Digital Amplifier represents the culmination of a decade long NAD research project, capped by three years of intense development. The result fully justifies the investment. We believe that the M2 sets new benchmarks for both measured performance and subjective musical quality.

     C 275BEE Stereo Power Amplifier; 150w x 2
    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. A carefully engineered 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!
