Description
The NAD M66 Masters BluOS Streaming DAC-Preamplifier is a revolutionary hi-fi component that combines an audiophile-grade DAC with a high-resolution multi-room music streamer. Featuring Dirac Live Room Correction and Dirac Live Bass Control, its elegant design and vibrant 7″ touchscreen exudes quality and class. Pair it with NAD’s M23 power amplifier for a stunning system that excels technologically, sonically, and visually.
Music Everywhere
Featuring a high-resolution network streamer based on the acclaimed BluOS multi-room music-management system, the NAD M66 provides access to more than 20 streaming services, including several that offer lossless and high-resolution audio.
NAD M66 integrates Dirac Live Room Correction and Dirac Live Bass Control. Connect the supplied calibrated microphone to the M66’s USB port and then launch the Dirac Live app on a smart device or personal computer. The app will walk you through the calibration process, and then generate correction filters that compensate for acoustic problems like standing waves and unwanted reflections.
Peak Performance
At the heart of the NAD M66 digital section are ESS Technology’s flagship Sabre DAC and ADC chips. These audiophile-grade designs are known for their exceptionally wide dynamic range, ultra-low noise and distortion, and outstanding time-domain performance.
Connect Everything
With its full suite of analogue and digital inputs, the NAD M66 can accommodate all your source components. Vinyl fans will appreciate the M66’s ultra-quiet MM/MC phono stage, which features precise RIAA equalization, high overload margins, and an innovative circuit that suppresses the infrasonic noise that is always present with vinyl playback without affecting bass response.
Future Forward
NAD M66 Masters represents the pinnacle of what is technically achievable in a two-channel preamplifier today, and will maintain its technological leadership for decades to come. On the rear panel are two expansion slots that support MDC2, the latest generation of NAD’s Modular Design Construction future-proofing technology. As technology evolves, this will enable M66 owners to add new capabilities simply by inserting an MDC2 module into one of the slots.
