The Masters M66 BluOS Streaming DAC preamplifier is not only the most advanced preamplifier NAD has ever offered, it represents an entirely new class of discrete hi-fi components. In addition to a wealth of inputs including MM/MC Phono and HDMI eARC, the M66 includes an audiophile-grade D/A converter and a high-resolution multi-room music streamer.

In addition to full-bandwidth Dirac Live Room Correction, the M66 features Dirac Live Bass Control, which allows each connected subwoofer to be controlled independently to ensure consistent playback throughout the listening room. Combining Dirac Live Room Correction and Dirac Live Bass Control, the M66 delivers more precise in-room performance than any other two-channel component ever offered.

With its elegant aluminum housing, smooth digital volume control and dynamic 7″ touchscreen, the M66 exudes class and quality. Visually, sonically and technologically, it is the ideal complement to the award-winning Masters M23 power amplifier from NAD. Of course, the Masters M66 BluOS Streaming DAC preamplifier can be paired with any high-performance amplifier.

music everywhere

The M66 is a high-resolution network streamer based on the renowned BluOS multi-room music management system and provides access to more than 20 streaming services, including several that offer lossless and high-resolution audio. Using the intuitive BluOS app on a smart device or PC, listeners can play music from their favorite streaming service, personal music library and thousands of internet radio stations in up to 24-bit/192 kHz resolution. Like all BluOS-enabled components, the M66 also has full MQA decoding and rendering capability.

With BluOS you can listen to music in just one room or share music over your home network with up to 63 other BluOS-enabled components from NAD and other hardware partners. The M66 easily integrates with home control systems from Control4, Crestron, ELAN, RTI, URC and others. Listeners can also control playback by voice via Amazon Alexa or Apple Siri.

Perfect response

Dirac Live room correction and Dirac Live bass control are integrated into the M66. Connect the included calibrated microphone to the USB port of the M66 and then launch the Dirac Live app on a smart device or a PC. The app guides you through the calibration process and then creates correction filters that compensate for acoustic problems such as standing waves and unwanted reflections. You'll benefit from more structured bass, improved tonal accuracy, vastly improved clarity and focused imaging.

As the first stereo component, the M66 has four balanced and four unbalanced subwoofer outputs and is equipped with Dirac Live Bass Control, which allows independent calibration of multiple subwoofers. Dirac Live Bass Control optimizes the subwoofer output in both frequency and time domains, ensuring a seamless fusion between subwoofer(s) and main speaker(s), as well as smooth, consistent bass reproduction across the entire listening range and not just in the sweet spot.

Highest performance

At the heart of the M66's digital section are the Saber DAC and ADC chips from ESS Technology. These audiophile designs are known for their exceptionally wide dynamic range, extremely low noise and distortion, and outstanding time domain performance.

The M66 is the first component to feature NAD's innovative Dynamic Digital Headroom (DDH) circuit. When enabled in the BluOS app, DDH eliminates digital inter-sample peak clipping distortion that can occur during digital-to-analog conversion with sudden high-frequency transients. The advantages are particularly noticeable with percussion instruments: Rimshots are more powerful but less shrill; Cymbals appear more realistic and less splashy.

For volume control, the M66 uses a high-precision resistor cascade circuit. Compared to traditional analog circuitry, the M66's digital volume control significantly reduces thermal and associated distortion, maximizes dynamic range and provides more precise left and right channel matching across the volume range.

By default, analog signals are converted to digital signals, so features such as Dirac Live Room Correction and Bass Control are available for all sources. However, the M66 features a selectable analog direct mode that bypasses all digital processing, as well as separate signal paths for analog and digital sources. Internally, the analog and digital sections are physically separated from each other and shielded by their own power supplies, so that the analog signals are not affected by digital interference when the analog direct mode is activated. The BluOS app even lets you disable the M66's Wi-Fi and Bluetooth circuitry to avoid RF interference.
