Should you pay US$779 for a used NAD C390DD, or is this a genuine bargain? At US$779, this asking price sits well below the typical used market for the C390DD, which generally ranges from US$1,200 to US$1,600 depending on included modules and condition, making this a strong deal or clear bargain. The C390DD is highly regarded as a direct descendant of NAD’s flagship M2, delivering 150Wpc into 8 ohms with advanced room-equalization features and modular input boards that allow customization up to 14 inputs. Its combination of high power, digital versatility, and original-NAD engineering makes it a standout in the US$3k DAC-amp class, and at US$779 with no noted defects, this listing represents a compelling buying opportunity for enthusiasts seeking performance and flexibility without the premium price.

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.
