About the M66

The NAD M66 is a revolutionary high-fidelity streaming DAC and preamplifier that combines audiophile-grade digital-to-analog conversion with advanced multi-room streaming capabilities. It features a 7-inch touchscreen for intuitive control and supports over 20 streaming services including Amazon Music HD, Apple Music (AirPlay 2), Spotify Connect, Tidal Connect, and Qobuz. The M66 incorporates Dirac Live Room Correction and Dirac Live Bass Control for precise acoustic optimization, including seamless integration of up to four subwoofers with independent calibration. It uses flagship ESS Sabre ES9038PRO DAC and ES9822PRO ADC chips, and introduces NAD's Dynamic Digital Headroom (DDH) technology to eliminate digital inter-sample peak clipping distortion, enhancing the realism of percussion and cymbals. The unit offers a wide range of inputs including HDMI eARC, balanced XLR, RCA, optical, coaxial, AES/EBU digital inputs, and an ultra-quiet MM/MC phono stage with RIAA equalization. It supports both wired Ethernet and Wi-Fi (802.11ac) networking, Bluetooth 5.0 with aptX-HD and LDAC, and is Roon Ready. The M66 also features a high-precision resistor-ladder volume control circuit for minimal distortion and accurate channel matching, plus two MDC2 expansion slots for future upgrades. Its elegant aluminum chassis and comprehensive control options including Amazon Alexa and Apple Siri voice control make it a versatile and future-proof centerpiece for any high-end audio system.
