Cambridge Audio Azur 851N is the flagship reference network player. This is a "Three-in-one" component that acts as a high-end network streamer, a premium DAC, and a digital pre-amplifier. It delivers breathtaking detailed sound, often described as a "giant-killer" for it's ability to compete with much more expensive streamers. It features twin Analog Devices DACs in dual differential mode and proprietary ATF2 upsampling to 24-bit/384kHz, which eliminates digital jitter. It can stream Tidal, Spotify Connect, Apple AirPlay, Radio Stations and more.What's in the package: Original packing, Manuals, Remote Control, Power Cord & BT100 Bluetooth Accessory. This unit is in Audiophile condition with many years of musical enjoyment.
At US$750, this Cambridge Audio Azur 851N is a clear bargain compared to the obvious alternative of buying a modern streamer-DAC at this price, which rarely matches its flagship-grade performance. The asking price sits well below the typical used market, which generally ranges from US$850 to US$950 for units in good condition, and is far below its original retail of US$1,499–US$1,799. This listing hits the low end of the used spectrum, making it a strong deal for anyone seeking high-end sound without the new-price tag.
The 851N remains well-regarded for its dual AD1955 DACs, aggressive upsampling to 24-bit/384kHz, and robust digital preamp features including AirPlay, Spotify Connect, and UPnP/NAS support. Its soundstage, tonal richness, and flexibility make it a standout in the used hi-fi world, especially if the unit is from an original owner with no known issues. At US$750, this is a buying opportunity for enthusiasts who value performance over latest-gen connectivity.

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.
