NAD C 399 Hybrid Digital DAC Amplifier

The NAD C 399 HybridDigital DAC Amplifier is the flagship of the brand's Classic Series integrated amplifiers, legendary since 1972 for blending technical sophistication with unparallelled value. The C 399is the first Classic Series device to benefit from the nCore amplification platform used in the Masters Series and is also the first to carry the MDC2 platform to ensure lasting performance.
