NAD M66 BluOS Streaming Preamplifier / DAC

A Sabre-chip streaming DAC with voice control, wireless and smart control capability, XLR outputs, phonostage, and Dirac room correction

NAD's Masters series brings together hi-fi sound quality and rich feature content. The M66 streaming DAC and preamp has a vibrant 7" touchscreen, and pairs perfectly with the power amplifier, both sonically and visually. It is all housed in elegant aluminum casework that features a super-smooth digital volume control.

Connect the M66 either over Wi-Fi or use an Ethernet cable. Control is via the acclaimed BluOS app which provides access to over 20 streaming services, including several that deliver lossless and high-resolution audio.

Dirac Live Bass Control enables a seamless blend between the up to four subwoofers and main speakers, and smooth bass response throughout the listening area. An ultra-quiet MM/MC phonostage offers precise RIAA equalization, high overload margins, and an infrasonic filter. The dedicated headphone amplifier has low output impedance and very high output voltage capability.
