At £595, this sits right on the median of the recent comparable GBP listings, so it reads as fair market price rather than a bargain or an ambitious ask. It is not cheap enough to call a steal, but it is also well inside the normal range versus the £569 to £742 spread.
That’s still a sensible buy if you want a serious, well-built integrated amp: the 851A is Cambridge’s flagship Azur integrated, known for 120W per channel into 8 ohms, strong grip, and a clean, muscular presentation with proper bass control. At this level, the upside is getting a high-end-feeling amp for mid-market money; just make sure it’s complete and functioning cleanly, since age and remote/power-switch issues are the main practical things to check.

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.
