NAD 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.
