At £300, this sits just above the £277 median and a touch under the £307 75th percentile, so it reads as a fair, slightly firm asking price rather than a bargain. It is not expensive enough to be a red flag, but there is little room for wear, missing bits, or uncertainty if you want to feel good about the buy.
The 640R is still well liked for its muscular, clean amplification and its ability to drive real speakers confidently; it was one of Cambridge’s stronger-sounding multichannel receivers. For a clean, working example with the remote and sensible ownership history, £300 can make sense. The main buyer check is age-related functionality: HDMI switching, caps, and long-term stability matter more than cosmetics on a receiver this old.

Cambridge Audio emerged from the innovative spirit of 1960s Britain, founded in Cambridge, United Kingdom, by a group of young engineers who spun off from Cambridge Consulting Group. Established in 1968, the brand launched with the groundbreaking P40 integrated amplifier—the first to employ a toroidal transformer, setting a new standard for dynamic power delivery in hi-fi design that endures in high-end gear today. This heritage of British engineering excellence propelled decades of award-winning products, navigating ownership changes including a revival under entrepreneur Vince Adams and acquisition in 1994 by Julian Richer and James Johnson-Flint of Richer Sounds.
The brand excels across core hi-fi categories, renowned for integrated amplifiers like the iconic A1 and P-series, alongside streaming DACs, network players, turntables, and all-in-one systems that prioritize pure analogue warmth and digital precision. Speakers, headphones, and cables round out a cohesive ecosystem, emphasizing accessible high performance without excess frills.
Positioned firmly in the mid-tier market, Cambridge Audio delivers premium British sound—detailed, rhythmic, and uncolored—at prices that democratize quality for discerning buyers. Free from corporate bloat, it holds a reputation for reliability and value, appealing to enthusiasts seeking sophisticated hi-fi that punches above its weight rather than chasing ultra-high-end esoterica.
