Unknown condition keeps this from being an automatic bargain, but at US$1,100 it lands right on the median of recent used comps, so the ask is fair rather than cheap. It is not overpriced, and if the unit is clean, fully functional, and complete, it sits in normal market territory for a desirable piece.
The C 658 is well liked because it’s a flexible DAC/preamplifier with strong streaming and digital inputs, solid app control, and the easy, polished NAD sound many systems benefit from. Best-case upside is a tidy, ready-to-run example with the remote, original packaging, and no connectivity quirks; if those are present, this is a sensible buy at this price.
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.
