This is a seller’s market only if the example is unusually clean; at £245, this one is clearly overpriced against the used market. Recent comparable asking prices put the median at £131, with the upper quartile at £170, so £245 is roughly £75 above even that top-end benchmark. With condition listed as unknown, there is no obvious justification for the premium.
The 650A remains a capable, muscular analogue integrated, offering 75 watts per channel, plenty of inputs, a broad stereo image and strong midrange detail. It is a good match for listeners who value pace and clarity, though some systems may find its treble slightly forward. At this price, insist on a full demonstration: older examples can develop intermittent channel or speaker-relay issues. A sensible buy would be nearer £130–£170, with the current ask requiring exceptional condition, accessories and service history.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
