Marked as “unknown” condition, this A$1,025 asking price is a strong deal, landing well below the 25th percentile of A$1,042 and roughly A$84 under the A$1,109 median from six recent AUD comps. In the used market, unit prices for the 851A typically cluster between A$1,042 and A$1,140, so this listing is a clear bargain if the unknown condition doesn’t hide a major fault.
The 851A remains a well-regarded integrated for its 120Wpc into 8 ohms, balanced XLR inputs, eight RCA line inputs, and rare tone controls at this class level. It’s an analogue-only amp (no internal DAC), prized for clean power and musicality. If the unit is original-owner, includes the remote and manual, and shows no signs of overheating or relay chatter, this is a buying opportunity—especially at a price that rewards a quick, careful inspection.

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.
