At £170, this Cambridge Audio Azur 651A is a genuine bargain, sitting well below the 25th percentile of £189 from your recent GBP listings and far under the £319 median. With the original new price having been around £449, this asking price represents a massive discount for a well-loved integrated amplifier that still delivers 75 watts per channel and includes a built-in USB DAC.
The 651A is highly regarded for its warm, musical sound quality that rivals amplifiers costing nearly three times as much, making it an excellent entry into high-end hi-fi. Its inclusion of modern digital connectivity via USB adds significant timing upside for a buyer wanting to connect a computer or streamer without extra hardware. At this price, it’s a clear buying opportunity for a clean, capable unit that balances vintage tone with contemporary convenience.

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.
