£287 sits just above the median of £276 and well within the fair range between the 25th percentile (£246) and 75th percentile (£290), making this a solid, honest price for a classic unit rather than a bargain or an ambitious ask. When the NAD 3155 first retailed, it cost around £279, so this used price reflects its enduring value without inflating it.
This amplifier is a genuine buy opportunity because it delivers surprisingly clean sound with 40W per channel, a built-in phono stage, and that distinctive NAD warmth that still holds up today. Its robust build, vintage appeal, and original-owner condition (if confirmed) make it a rewarding project for enthusiasts who appreciate simple, reliable analog power. With maintenance like contact cleaner on switches and pots, it can perform flawlessly, offering a meaningful upgrade over modern budget alternatives at a fair entry point.

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.
