The CX 81 Mk2 sits in Cambridge Audio’s well-liked integrated amp sweet spot: refined, capable, and easy to live with. At £690, this is a fair ask against the recent used median of £642 and still comfortably below the £1,023 upper quartile, so it’s not a bargain-bin score but it is priced in the right neighborhood.
What makes it worthwhile is the mix of clean power, good streaming-era system flexibility, and generally strong everyday musicality for the money. If the listing really is mint and includes the remote and original packaging, that adds confidence and resale ease; at this price, I’d mainly want proof of low use and a clean functional check rather than looking for faults.

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.
