Product Details ＋

A revolutionary hi-fi product from NAD Electronics, the Masters M66 combines an audiophile-grade DAC with a high-resolution multi-room music streamer. Not only is the Masters M66 BluOS streaming DAC-preamplifier the most advanced preamplifier NAD has ever offered, it represents an entirely new class of hi-fi separate components. With a plethora of inputs, including MM/MC phono and HDMI eARC, the M66 is a highly-capable, compatible amplifier.

Dragon Cable Recommendation: We recommend pairing the NAD Electronics M66 Streaming DAC Preamplifier with the Black Dragon Power Cable, Silver Dragon Network Cable, and Silver Dragon Interconnect Cable. The is the ultimate power cable designed to be dead quiet and reject all EMI and RFI interference. 4-11Awg Stranded high purity slow drawn Copper conductors are used per cable in a star Quad configuration. The cable has a single 100% coverage shield but can be doubled up for noisy environments plus it is relatively flexible. Pair the M66 with your favorite subwoofer and you’ve got the perfect hifi setup.

Choose our with RCA connectors to integrate the M66 with other audio devices in your setup. Sold in Pairs, the Silver Dragon V2 is our top-of-the-line silver conductor-based interconnect. With a braided geometry and amazing shielding, this interconnect is a remarkable solution where noise isolation is key. The braided geometry itself acts as a noise rejection and the shield aso adds more durability to the cable for runs on a studio floor. Lastly, the will provide a stable network connection to the M66 during use. High speed, low latency, and low jitter perfect bit rate communication between audio components can be maximized by using solid core silver conductors. The Silver Dragon Network Cable uses 8 solid core 99.999% pure silver 26AWG Teflon insulated conductors.

Connect Everything

The M66 is a highly-capable Streaming DAC Preamplifier with a full suite of analog and digital inputs, accommodating all of 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. For TV and home theater, movie viewing, there’s an HDMI eARC port for connection to an HDTV. Other options include two coaxial and two optical S/PDIF inputs, an AES/EBU balanced digital input, two pairs of RCA line-level analogue inputs, and one pair of XLR balanced inputs for connection to a power amplifier.

Additionally, the M66 has four unbalanced RCA and four balanced XLR subwoofer outputs. The M66’s dedicated headphone amplifier has very low output impedance and very high maximum output voltage, enabling it to drive demanding high-impedance studio monitor headphones. The M66 also has Bluetooth connectivity, with support for the AAC, LDAC, and aptX HD codecs.

Stream Music Everywhere at Your Fingertips

Featuring a high-resolution network streamer based on the acclaimed Bluesound BluOS multi-room music-management system, the M66 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 personal computer, listeners can play music from their favourite streaming service, their personal music libraries, and thousands of Internet radio stations, in resolution up to 24-bit/192kHz. Like all BluOS-enabled components, the M66 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 additional BluOS-enabled components from NAD and other hardware partners. The M66 integrates easily with home-control systems from Control4, Crestron, ELAN, RTI, URC, and others. Listeners can also control playback by voice using Amazon Alexa or Apple Siri. As a Roon Ready component, the M66 can be integrated into an existing Roon ecosystem for even more flexibity than what's imaginable.

Advanced Technologies, Elegant Design

The Masters M66 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.

The M66 integrates Dirac Live Room Correction and Dirac Live Bass Control for the most accurate in-room performance than any two-channel component ever offered. With four balanced and four single-ended subwoofer outputs and the Dirac Live Bass Control, users can connect multiple subwoofers and calibrate them independently. Dirac Live Bass Control optimizes subwoofer output in both the frequency and time domains, achieving a seamless blend between the subwoofer(s) and main speakers, and delivering smooth, consistent bass response through the entire listening area, not just in the sweet spot. 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. You’ll enjoy more textured bass, improved tonal accuracy, vastly improved clarity, and more focused imaging.

Everything about the NAD Masters M66 BluOS streaming DAC-preamp is intended to inspire pride of ownership: the gorgeous 7″ touchscreen, the elegant aluminium casework, and the silky-smooth digital volume control. With its leading-edge technology, unmatched versatility, and superb build quality, the Masters M66 is truly a masterpiece of sound.

Peak Performance

At the heart of the M66’s digital section are ESS Technology’s flagship Sabre digital-to-analog converter 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. The M66 is the first component to feature NAD’s innovative Dynamic Digital Headroom (DDH) circuitry. which can be activated through the BluOS app. This feature effectively eliminates digital inter-sample peak clipping distortion, resulting in more impactful yet less strident percussion sounds, particularly noticeable in rim shots and cymbals.
