This is a strong deal. At £60, it sits well below the 25th percentile of recent UK asking prices at £86, and comfortably under the median of £105, so it looks like an easy buy if it’s working properly.
The 640A is a respected older Cambridge integrated: lively, clean, and capable of proper musical drive, with enough power for most sensible speakers. It earned a strong reputation for being a musical all-rounder, and at this price the upside is obvious. Just make sure it powers up cleanly, switches inputs without noise, and the remote and original accessories are present if you care about completeness; otherwise, this is exactly the sort of used amp enthusiasts like to snap up.

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.
