A fair ask, and close enough to market that it’s not a steal, but it’s reasonable for a working example. The freshest active reference I found sits at about US$192, which puts US$191 essentially on the money; older used sales can land lower, but that’s not a strong argument against this listing if it’s complete and healthy.
The CD4 has a good reputation as a musical, no-nonsense player, and it’s the kind of Cambridge piece enthusiasts still buy for straightforward CD playback rather than flash. At this price, the real upside is a clean, tested unit with the remote and proof it reads discs quickly and quietly; if those boxes are ticked, it’s a sensible buy.
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.
