At US$849, this NAD C390DD is a strong bargain, sitting well below the typical used market range of roughly US$1,100–US$1,400 for a unit in good condition. The asking price is nearly 40% off its original US$2,600 MSRP and significantly lower than recent European used listings that convert to US$1,350–US$1,700, making this an excellent value opportunity for a savvy buyer.
The C390DD is well-regarded for bringing NAD’s flagship M2 Direct Digital technology to a more accessible price point, delivering 150W per channel with ultra-low distortion (0.005% THD) and precision 24-bit/192kHz DAC performance. Its modular design allows owners to add phono or HDMI modules, and it includes Room EQ for speaker optimization—a feature even the M2 lacked at launch. If this listing includes the original remote and any added modules, the upside is even greater, turning a fair-priced amp into a genuine standout deal.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
NAD Electronics was founded in 1972 in London by a group of European audio importers frustrated with the hype surrounding Japanese hi-fi products. Led by visionary American executive Martin L. Borish and brilliant engineer Bjorn Erik Edvardsen, the company emerged from a quest to deliver high-performance audio at accessible prices. Their breakthrough came with the NAD 3020 integrated amplifier, the best-selling hi-fi amp in history, which embodied a philosophy of stripping away non-essentials to prioritize pure sound quality.
The brand focuses on core hi-fi categories, excelling in amplifiers—pioneering Class A/B, Class G, and hybrid digital designs—alongside integrated receivers, AV processors, turntables, CD and cassette players, and modern streamers. While not venturing into speakers, headphones, or cables, NAD emphasizes source components and amplification that integrate seamlessly into home theater and custom installation setups, always upholding principles of innovation, simplicity, performance, and value.
Today, as part of Canada's Lenbrook Group and sold in over 80 countries, NAD holds a commanding mid-tier position in the market, revered by audiophiles for affordable excellence rather than ultra-high-end excess. Its "Truth in Power" legacy earns cult status among knowledgeable buyers seeking reliable, award-winning gear that punches above its price, blending vintage heritage with contemporary streaming and hybrid tech.
