A solid, well-regarded integrated amp, but this asking price lands above the current used norm. With a median of US$770, a 75th percentile of US$799, and a listed price of US$900, it reads as a bit ambitious unless the unit is unusually pristine or includes extras.
That said, the 851A is popular for good reason: 120W into 8 ohms, strong drive, lots of inputs, and a clean, full-bodied presentation that suits a wide range of speakers. If the condition is genuinely excellent, it’s still a worthwhile buy for someone who wants a robust, no-nonsense analog integrated; just expect to negotiate, since this is pricing above the typical market pocket rather than a standout deal.
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.
