The 851E has a strong reputation as a clean, neutral, fully analogue preamp with very low noise and excellent transparency, so it sits in that sweet spot for serious two-channel systems. At £645, this looks fair to slightly good rather than a bargain; used examples of this class often land around the mid-hundreds, and the original £1,999-ish launch price puts the ask at a sensible fraction of new.
What makes it worth buying is the combination of honest sound, lots of useful inputs, and the fact that it was one of Cambridge’s better-regarded “851” pieces. If it’s complete, tidy, and from a careful owner, it’s an easy-to-like purchase for someone wanting a proper standalone preamp without paying boutique money. I’d mainly want to confirm the remote, all input functions, and smooth volume operation before handing over the cash.

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.
