Possessing exact copies of the Studio Master recordings has been the audiophile’s dream from the beginning of high fidelity playback.Even the best system cannot regain what has been lost in a recording, reduced in fidelity to fit on a CD or LP, and the limitations of previous media has always meant a compromise in fidelity. Unless you were lucky enough to visit a recording studio, you could never hear the most accurate form of the recording—the Studio Master. This is now changing with the increasing popularity of HD downloads—great news for anyone who loves music. The problem, however, is the computer, which was not built for audio performance. Now with NAD’s Masters Digital Music Suite, you can download, listen, stream, and store precious HD recordings without a computer, completely shaking up the way you enjoy HD music. The M50 Digital Music Player is where most of the processing and control functions are located, and acts as the brain of the revolutionary Masters Digital Music Suite.

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.
