Condition is unknown, so at US$299 this sits above the usual used market: it’s over the US$200 median and even past the US$265 75th percentile, so I’d call it ambitious unless the unit is unusually clean, serviced, or comes with extras. For a plain unrestored example, I’d want more cushion on price.
That said, the 2100 is a respected vintage NAD power amp with the kind of punchy, musical presentation people still chase for modest systems and classic pairings. If it’s tested, quiet, and original-owner with solid cosmetics, the appeal is real; just make sure the protection relay, channel balance, and any service history check out before paying top-end money.
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.
