New, the NAD M66 was around £3,999, so £2,995 is a substantial saving—roughly 25% below current retail. Against the wider used-listing data, though, it sits far above the £397 75th percentile and is therefore an ambitious asking price rather than an obvious bargain.
The M66 remains an exceptionally capable one-box control centre: excellent BluOS streaming, a serious DAC, MM/MC phono, HDMI eARC, balanced connectivity and unusually comprehensive Dirac Live room correction, including bass management for multiple subwoofers. That feature set makes it particularly attractive for a modern, highly integrated system, and a clean example with the calibration microphone, remote, packaging and transferable accessories could justify paying a premium. Still, at £2,995, negotiate firmly; a lower figure would better reflect used-market value and reduce the risk of buying into rapid depreciation.

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.
