As the new flagship of NAD’s Classic series, the C 399 HybridDigital DAC Amplifier redefines the brand’s legacy of performance and long-term value. It features NAD’s advanced Hypex HybridDigital nCore amplifier technology—previously reserved for the premium Masters Series—and delivers exceptionally clean, powerful sound.
