£105 is fair to a touch keen for a Cambridge Audio 640P in unknown condition; it is not a standout bargain, but it is still within sensible used-money for a well-known budget phono stage. The 640P earned a strong reputation for giving clean, lively MM/MC performance and more flexibility than most phono stages at this level, so the model itself is easy to justify if the asking price is clean and the unit is proven working.
What makes it appealing is the punchy, low-noise sound and the useful MM/MC switching, plus the subsonic filter, which makes it a genuinely practical buy for a lot of vinyl setups. If it’s been well cared for and comes with the original PSU, that helps; if condition is only described as unknown, I’d want confirmation it powers up quietly, switches properly, and isn’t suffering from the usual age-related niggles before paying the full £105.
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.
