When new, the Cambridge Audio Azur 651A cost around £450; at £261, this used example sits above the £196 median of 17 comparable listings, but remains below the £290 upper quartile. That makes it a fair-to-good price rather than a bargain, assuming it is fully tested and in tidy condition.
It is a capable, muscular integrated amplifier with 75 watts per channel, authoritative bass, clean timing and a useful spread of analogue inputs, plus USB, pre-out, subwoofer output and speaker A/B switching. The USB input is limited to 16-bit/48kHz, but that is hardly a deal-breaker for a straightforward computer source. Check that the remote is included, both channels are quiet, the controls are free from crackle and the speaker protection behaves normally; at this price, those details matter.

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.
