In the C 3050 Stereophonic Amplifier, NAD’s 50-year history of innovation meets the future of hi-fi. With its dual VU meters, push-button input selectors, walnut-finished vinyl-clad cabinet, and 1970s cursive-style branding, the C 3050 recalls the components that helped a generation of music-lovers discover the joys of great audio. With its 100-watt-per-channel HybridDigital UcD amplifier and Texas Instruments high-resolution differential DAC, the C 3050 delivers sound that will thrill today’s discerning listeners. And thanks to NAD’s MDC2 future-proofing technology, C 3050 owners can add leading-edge capabilities like BluOS high-resolution multi-room streaming and Dirac Live room correction.
