Description
As the new flagship of NAD’s Classic series of integrated amps, the C 399 HybridDigital DAC Amplifier takes NAD’s commitment to lasting value and sonic excellence to a whole new level.
The C 399 employs NAD’s Hypex HybridDigital nCore amplifier circuitry, which until now has been available only on Masters Series amplifiers. Its digital section is built around a 32-bit/384kHz ESS Sabre DAC, the same chip used in NAD’s acclaimed M10 and M33 Masters Series amplifiers.
The C 399 is the first amplifier to incorporate the latest generation of NAD’s Modular Design Construction (MDC) technology. MDC2 lets users add optional modules that provide functions such as BluOS multi-room music streaming and Dirac Live room correction.
