{"product_id":"m66","title":"M66","description":"\u003cp\u003eThe Masters M66 BluOS Streaming DAC Preamplifier is not only the most advanced preamplifier NAD has ever offered, it represents an entirely new class of separate hi-fi components. In addition to a wealth of inputs, including MM\/MC phono and HDMI eARC, the M66 includes an audiophile DAC and a high-resolution multi-room music streamer.\u003cbr\u003eIn addition to full-bandwidth Dirac Live Room Correction, the M66 features Dirac Live Bass Control, which can independently control any connected subwoofer to ensure even playback throughout the listening room. By 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.\u003cbr\u003eWith its elegant aluminum chassis, smooth digital volume control and dynamic 7″ touchscreen, the M66 exudes class and quality. Visually, sonically and technologically, it is the ideal complement 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.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eMusic Everywhere\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe M66 is a high-resolution network streamer based on the renowned BluOS multiroom music management system, offering access to more than 20 streaming services, including several that offer lossless and high-resolution audio. With 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 at up to 24-bit\/192kHz resolution. Like all BluOS-enabled components, the M66 features full MQA decoding and rendering capability.\u003cbr\u003eWith BluOS, you can listen to music in just one room or share music across your home network with up to 63 other BluOS-enabled components from NAD and other hardware partners. The M66 integrates seamlessly 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.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003ePerfect Response\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe M66 incorporates Dirac Live Room Correction and Dirac Live Bass Control. Connect the included calibrated microphone to the M66's USB port, then launch the Dirac Live app on a smart device or PC. The app guides you through the calibration process and then generates correction filters that compensate for acoustic problems such as standing waves and unwanted reflections. You'll benefit from more structured bass, improved tonal accuracy, significantly improved clarity, and focused imaging.\u003cbr\u003eAs the first stereo component, the M66 features 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 subwoofer output in both the frequency and time domains, ensuring seamless blending between subwoofer(s) and main speaker(s), as well as smooth, consistent bass reproduction across the entire listening area, not just the sweet spot.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eHighest Performance\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAt the heart of the M66's digital section are ESS Technology's Sabre DAC and ADC chips. These audiophile designs are known for their exceptionally wide dynamic range, extremely low noise and distortion, and outstanding time-domain performance.\u003cbr\u003eThe M66 is the first component to feature NAD's innovative Dynamic Digital Headroom (DDH) circuitry. 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 benefits are especially noticeable with percussion instruments: rimshots are punchier but less shrill; cymbals sound more realistic and less splashy.\u003cbr\u003eFor volume control, the M66 uses a high-precision resistor cascade circuit. Compared to conventional analog circuits, 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 entire volume range.\u003cbr\u003eBy default, analog signals are converted to digital, so features like 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 and shielded by their own power supplies, so analog signals are not affected by digital interference when Analog Direct mode is enabled. With the BluOS app, you can even disable the M66's Wi-Fi and Bluetooth circuits to avoid RF interference.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eConnect Everything\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWith its numerous analog and digital inputs, the M66 can accommodate all your source components. Vinyl enthusiasts will appreciate the M66's ultra-quiet MM\/MC phono stage, which features precise RIAA equalization, high overload margins, and innovative circuitry that suppresses infrasonic noise always present in vinyl playback without compromising bass reproduction. For TV and movie playback, there's an HDMI eARC port for connecting to an HDTV. Other options include two coaxial and two optical S\/PDIF inputs, a balanced AES\/EBU digital input, two pairs of RCA analog line-level inputs, and a pair of balanced XLR inputs.\u003cbr\u003eIn addition to unbalanced RCA and balanced XLR outputs for connection to a power amplifier, the M66 features 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, allowing it to drive demanding high-impedance studio monitor headphones. The M66 also features Bluetooth connectivity with support for AAC, LDAC and aptX HD codecs.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eForward into the Future\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 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 future-proof Modular Design Construction technology. As technologies evolve, M66 owners can add new features by simply inserting an MDC2 module into one of the slots.\u003cbr\u003eEverything about the NAD Masters M66 BluOS Streaming DAC Preamplifier is designed to inspire pride of ownership: the beautiful 7-inch touchscreen, the elegant aluminum chassis, and the silky-smooth digital volume control.
