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 boasts a full roster of audiophile-grade features. In addition, Modular Design Construction allows new features and functionality to be added now or in the future. These features leverage some of the most advanced digital audio thinking to date, resulting in a truly outstanding product. NAD’s DirectDigital™ processing, as well as a fully balanced Class-A buffer stage, provide amazing accuracy and transparency with a completely silent background. The M12 interfaces with all digital or analogue musical sources, and renders them perfectly to power amplifiers and active loudspeakers with its balanced or single-ended outputs. By adding the M12 to your system, you will finally get to hear your music in the best audio quality possible from every imaginable source, from vinyl to High Res digital.
