£172 looks like a fair-to-good asking price, sitting comfortably above the £114 median but below the £248 upper quartile for comparable used examples.
The Duo is a well-regarded, versatile stage: it handles both MM and MC cartridges, offers sensible low-noise performance, and includes a genuinely useful 6.3 mm headphone amplifier with its own volume control. That makes it more than a basic phono box, particularly for late-night vinyl listening or a second system. At £172, the value is solid if it includes the power supply and is fully tested; check that the MM/MC switching, headphone output, RCA sockets, and balance control work properly. Its fixed MC loading is the main limitation for demanding cartridge matching, but it is not a serious drawback at this price.

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.
