US$200 is a bargain for an NAD M15 if it’s functional and reasonably complete. Even as an older processor, the used market typically sits far above this—roughly in the US$800 to US$1,400 zone based on recent asking prices and past sales listings—so this is well below normal going rates.
What makes it worth a look is the M15’s reputation as a solidly built Masters Series pre/pro with THX Ultra II, good DACs, and the kind of robust analog feel NAD was known for in that era. At this price, the upside is strong for someone who wants a capable legacy theater processor or a vintage surround centerpiece. The only real caveat is age: confirm it powers up cleanly, switches inputs properly, and includes the remote and any needed calibration bits, because replacements can be the annoying part on older processors.
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.
