The M66 features Dirac Live Room Correction and Dirac Live Bass Control, technologies that deliver more accurate in-room response than any other two-channel component ever offered. These advanced features help deliver an exceptionally precise and immersive soundstage. The M66’s ability to present music with absolute precision and laser focus makes it a top choice for audiophiles looking to delve deeper into their music collection.

Connectivity

The M66 can accommodate all your source components with its comprehensive range of analog and digital inputs. For vinyl enthusiasts, there is an ultra-quiet MM/MC phono stage with accurate RIAA equalization. For TV and movie viewing, the M66 has an HDMI eARC interface for connection to an HD TV. The M66 also features Bluetooth connectivity, with support for AAC, LDAC, and aptX HD codecs.

Network Player

It has Ethernet and Wi-Fi network connectivity, and the BluOS network streamer provides access to over 20 streaming services, including several that stream lossless and high-resolution audio. It also supports Apple AirPlay 2, Spotify Connect, Tidal Connect, and integrates seamlessly with smart home control systems such as Crestron, Control4, ELAN, RTI, URC, and others.

Technology

The M66 represents the pinnacle of what is technically achievable in a two-channel preamplifier today and will maintain its technology leadership for decades to come. On the rear panel are two expansion slots that support MDC2, the latest generation of NAD’s future-proof Modular Design Construction technology.
