    M66 NAD Masters M66 BluOS Streaming DAC-Preamplifier

    The Masters M66 BluOS Streaming DAC-Preamplifier is a revolutionary hi-fi component that combines an audiophile-grade DAC with a high-resolution multi-room music streamer. Featuring Dirac Live Room Correction and Dirac Live Bass Control, its elegant design and vibrant 7″ touchscreen exudes quality and class. Pair it with NAD’s M23 power amplifier for a stunning system that excels technologically, sonically, and visually.

    NAD Masters M66 BluOS Streaming DAC-Preamplifier

    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. In addition to a plethora of inputs, including MM/MC phono and HDMI eARC, the M66 incorporates an audiophile-grade DAC and a high-resolution multi-room music streamer.

    Along with the full-bandwidth version of Dirac Live Room Correction, the M66 features Dirac Live Bass Control, allowing independent control of each connected subwoofer, for smooth, consistent response throughout your listening room. The combination of Dirac Live Room Correction and Dirac Live Bass Control enables the M66 to deliver more accurate in-room performance than any two-channel component ever offered.

    With its elegant aluminum casework, super-smooth digital volume control, and vibrant 7″ touchscreen, the M66 exudes class and quality. Visually, sonically, and technologically, it’s an ideal match to NAD’s award-winning Masters M23 power amplifier. Of course, the Masters M66 BluOS Streaming DAC-Preamplifier can be paired with any high-performance amplifier.

    Music Everywhere

    Featuring a high-resolution network streamer based on the acclaimed 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 favorite 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.

    Perfect Response

    The M66 integrates Dirac Live Room Correction and Dirac Live Bass Control. 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.

    In a first for a stereo component, the M66 features four balanced and four single-ended subwoofer outputs and integrates Dirac Live Bass Control, which allows independent calibration of multiple subwoofers. 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.

    Peak Performance

    At the heart of the M66’s digital section are ESS Technology’s flagship Sabre DAC 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. When activated in the BluOS app, DDH eliminates digital inter-sample peak clipping distortion, which can occur during digital-to-analogue conversion with sudden high-frequency transients. The benefits are especially noticeable with percussion instruments: rim shots are more impactful but less strident; cymbals are more realistic and less splashy.

    For volume adjustment, the M66 employs an ultra-precise resistor-ladder control circuit. Compared to traditional analogue circuits, the M66’s digital volume control markedly reduces thermal and related distortions, maximizes dynamic range, and more accurately matches left- and right-channel output across the entire volume range.

    By default, analogue signals are converted to digital so that functions like Dirac Live Room Correction and Bass Control are available with all sources. However, the M66 has a selectable Analogue Direct mode that bypasses all digital processing, and separate signal paths for analogue and digital sources. Internally, the analogue and digital sections are physically separated and shielded from each other with their own separate power supplies sections, so that analogue signals are unaffected by digital interference when Analogue Direct mode is engaged. This results in distinct volume attenuation, superb left and right tracking and very low noise.

    Connect Everything

    With its full suite of analogue and digital inputs, the M66 can accommodate all 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 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.

    In addition to unbalanced RCA and balanced XLR outputs for connection to a power amplifier, 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.

    Future Forward

    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.

    Everything about the NAD Masters M66 BluOS streaming DAC-preamp is intended to inspire pride of ownership: the gorgeous 7″ touchscreen, the elegant aluminum 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.

    Manufacturer’s Pricing Policy

    Why do I need to contact you in order to place my order?

    As an authorized dealer for the product you are looking at, ProjectorScreen.com is bound by certain agreements with our manufacturer partners in how we display, price and sell certain products.

    Some items may not be able to be advertised below a certain price or any pricing at all and others may not be able to be added to a shopping cart via an “add to cart” button.

    If a competitor’s website has the same product but is not restricting the display/functionality in the same way that you see here on ProjectorScreen.com, than that competitor is likely NOT an authorized dealer.

    What does that mean for you as the customer? It is very likely that the manufacturer may not honor your products warranty, or that your product was never intended for the US market to begin with.

    If you have any questions regarding a specific product, please do not hesitate to contact us at (888) 392-4814.
