NAD M-12

Built for the future, the M12 is neither a typical DAC nor a typical preamplifier. In fact, the M12 is an ultra-high resolution digital audio hub that features a full range of audiophile features. In addition, Modular Design Construction offers new features and functionality that can be added now or in the future. These features make use of some of the most advanced digital audio features to date, resulting in a truly outstanding product. NAD's DirectDigital processing, along with a fully balanced Class A buffer stage, offers stunning accuracy and transparency with a completely silent background. The M12 connects to all digital or analog music sources and makes them perfectly suited for power amplifiers and active speakers with balanced or single-ended outputs. By adding the M12 to your system, you will finally hear your music in the best possible audio quality from any conceivable source, from vinyl to High Res digital.
