Condition is unknown, and at US$397 this lands above the typical used market anchor of US$324 and past the 75th percentile at US$360, so I’d call it ambitious unless the seller can show very clean cosmetics, recent service, or extras. Without that, it’s not an obvious bargain.
That said, the 3155 is a respected NAD integrated: muscular, straightforward, and generally easy to live with, with the kind of no-nonsense control and warmth that still makes older NAD gear appealing. If it’s been checked over and is original, complete, and quiet in operation, it can still be a worthwhile buy—but at this ask I’d want proof of health and maybe some room to negotiate.
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.
