At £200, this sits right on the median of your recent GBP comparables, so it reads as a fair ask rather than a bargain or an ambitious listing. Against the wider sample, it’s comfortably inside the normal market band too, landing well below the £439 75th percentile and above the £181 25th percentile.
That makes it a sensible buy if the amp is clean and fully working, because the 651A is a well-liked, no-drama integrated with solid drive, good control, and enough refinement to anchor a capable budget system. At this level, the main upside is simply getting a respected, properly specified amp without paying new-money premium; just confirm the usual basics like sound on both channels, smooth controls, and any included remote or original packaging if that matters to you.
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.
