Trickled down from NAD\u2019s Masters Series<\/strong>, the C 399\u2019s<\/strong> HybridDigital nCore amplifier can deliver 180 Watts per channel continuous power, and 250 Watts per channel instantaneous power. Highly efficient and remarkably powerful, the HybridDigital nCore amplifier can produce musical transients effortlessly. The design is renowned for its wide bandwidth, flat frequency response, clean clipping behaviour with instant recovery, high current capability, and stability into demanding low-impedance speaker loads. Noise and distortion are vanishingly low under all operating conditions. The minute levels of harmonic distortion are dominated by sonically benign second and third harmonics. The Hypex nCore design enables the C 399<\/strong> to produce neutral, distortion-free sound even at very high listening levels, with exquisite detail, superb portrayal of space, and thrilling dynamics.<\/p>\n Also trickled down from the Masters Series<\/strong> is the ESS Sabre 9028 high-resolution DAC, a design noted for near-zero levels of clock jitter, ultra-low noise and distortion, and wide dynamic range. This premium DAC enables the C 399<\/strong> to reproduce all your digital sources with amazing musicality, stunning clarity, and precise sound staging.<\/p>\n In 2007, NAD<\/strong> introduced Modular Design Construction, an innovative architecture for adding new functions to existing components. Many NAD<\/strong> products have rear-panel slots for MDC modules that perform HDMI switching, BluOS multi-room music streaming, Dolby Atmos surround processing, and other functions.<\/p>\n The C 399<\/strong> is the first product to feature NAD\u2019s<\/strong> new MDC2 architecture. By enabling two-way communications between the module and component, MDC2 opens up the future for new upgrades.<\/p>\n Equipped with Wi-Fi and Ethernet, the optional MDC2 BluOS-D module lets listeners play music from their favourite streaming services through the C 399<\/strong>, using the acclaimed BluOS Controller app for Android, iOS, macOS, and Windows. Like all BluOS-enabled products, the MDC2 BluOS-D has integrated support for dozens of streaming services; and supports Apple AirPlay 2, Spotify Connect, and Tidal Connect. Two-way communications also enable the MDC2 BluOS-D to stream music from sources connected to the C 399<\/strong> to BluOS-enabled components in other rooms.<\/p>\n The Dirac Live function lets you measure your room\u2019s acoustics using a supplied microphone and intuitive app, and then upload correction curves to the MDC2 BluOS-D. By compensating for acoustic anomalies in your listening environment, Dirac Live dramatically improves bass clarity, imaging, and timbral accuracy. Thanks to its two-way architecture, the MDC2 BluOS-D performs room correction for all sources connected to your C 399<\/strong>.<\/p>\nFuture Proof<\/h4>\n
