At US$5, this is a genuine steal against the typical used market: it sits far below the US$14 25th percentile and miles under the US$23 median, so I’d treat it as a strong bargain if the unit is basically complete and powers up. Even for a heavy, feature-rich digital source like this, that kind of pricing is the sort of number enthusiasts jump on fast.
What makes it worth the trouble is that the 851C is widely respected as more than a disc spinner: it’s a serious CD player, DAC, and digital preamp in one box, with the kind of build and sound quality that still appeals to system tinkerers and CD collectors. At this price, the upside is obvious; just make sure it’s not missing the remote, tray, or power cord, since those little omissions matter more when the asking price is this low.

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.
