This Cambridge Audio Azur 651A is a well-respected integrated amplifier that delivers gutsy power and clean sound, making it a standout in its class. The listing price of £818 is clearly ambitious, sitting well above the 75th percentile of £536 from our ground truth data on recent GBP listings, where the median is £319. This asking price exceeds typical used market values significantly, suggesting it is not a bargain but rather a premium ask for a unit that may not offer original-new condition or rare accessories to justify the cost.
Despite the high price, the Azur 651A remains a worthwhile buy for enthusiasts seeking reliable performance, strong bass control, and a toroidal power transformer that ensures stable output. Its reputation for sounding "gutsier" than the 351A model, coupled with features like USB DAC support in newer versions, adds meaningful upside for digital connectivity. If this unit is in original-owner condition with all accessories included, it could still represent a solid opportunity for a buyer who values proven hi-fi quality over strict price alignment. However, the lack of condition clarity warrants caution before committing at this level.
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.
