£100 is a fair-to-good asking price, sitting just below the £101 median and comfortably within the normal £82–£121 range for recent examples. It is not the bargain territory below £82, but it looks properly priced rather than ambitious.
The 640A remains a capable, unfussy integrated with a healthy 65 watts per channel, plenty of inputs, a clean, slightly warm presentation, and enough grip for a wide range of sensible speakers. The protection circuitry is a useful bonus, and the remote adds convenience, so confirm it is included. With condition listed as unknown, check both channels, source selection, headphone output, and listen for crackles or dropouts—used examples can develop switch or control issues. At £100, a fully working unit is a worthwhile buy.
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.
