NAD C3050 with BluOS

Stereophonic Amplifier

Created to celebrate 50 years of NAD innovation, the NAD C 3050 Integrated Amplifier blends vintage hi-fi charm with modern engineering. Inspired by the original NAD 3030 Stereophonic Amplifier, its walnut-finished cabinet, dual VU meters, and cursive-script logo honour the classic design while housing thoroughly modern circuitry. With the optional MDC2 BluOS-D module, the C 3050 adds high-resolution streaming and Dirac Live Room Correction (Includes Dirac Live® Limited Bandwidth licence and calibration microphone for room correction up to 500Hz - MDC2 BluOS-D card required). Recognised with multiple Product of the Year awards, it brings heritage styling and confident performance together in a uniquely engaging amplifier.
