NAD C 389 Hybrid Digital Amplifier

For over 50 years, the NAD brand has been synonymous with performance and value, and the C 389 HybridDigital DAC Amplifier continues that tradition. Its output stage is based on a customized version of NAD’s efficient HybridDigital UcD design, with multiple UcD amplifier modules in balanced bridged configuration and an innovative switch-mode power supply that provides ample reserves of current on demand. The C 389 can deliver a staggering 130W per channel continuously, with virtually unmeasurable distortion and noise through the audioband, and up to 350W per channel of instantaneous power, for effortless reproduction of musical transients.

The digital section features the same 32-bit/384kHz ESS Technology Sabre DAC chip used in NAD’s award-winning Masters M33 amplifier. Renowned for its exceptionally wide dynamic range, ultra-low noise and distortion, and near-zero levels of clock jitter, the ESS Sabre 9028 DAC enables the C 389 to deliver astonishing clarity and near-holographic imaging on all sources.

For movies and television, the C 389 has an HDMI eARC input so that you can play TV audio from through your high-fidelity speakers while controlling volume with the TV’s remote. Dual subwoofer outputs enable the C 389 to serve as the hub of a 2.1- or 2.2-channel system for music and movies. With the MDC2 BluOS-D installed, you can set crossover frequency with the BluOS app, for a seamless blend between the subwoofers and main speakers.
