Cambridge Azur 851N Upsampling Reference Network Player

Pin It
    The pinnacle of digital and streaming performance – the 851N is the ultimate network player. It’s features include; 24-bit/384kHz upsampling from all sources, native 24-bit/192kHz playback, USB, digital audio inputs and streaming over wi-fi including UPnP and NAS drives, Spotify Connect, Apple AirPlay, and DSD.

    The 851N takes almost any digital file from virtually any source and renders it to the highest possible standard. Every digital source becomes a hi-fi option; its wireless options include Wi-Fi, internet radio, Spotify, Airplay. Add an optional BT100 Bluetooth dongle, and any paired Bluetooth device is connected.

    Digital source components, such as a smartphone, set-top box or PC can connect via optical, co-axial or AES/EBU inputs, while other media are supported with Ethernet, USB and Audio USB. Music files in all the popular formats are supported, from MP3, through to FLAC/Apple Lostless and WAV 16-24 bit master files.

    Thanks to our proprietary ATF2 audio upsampling, the 851N upsamples everything to 24-bit / 384kHz. The audio signal then passes through two Analog Devices DACs in dual differential mode for the very finest digital to analogue conversion. As well as connecting the 851N to a traditional integrated amplifier, it can also be configured as a digital pre-amp allowing it to be connected directly to a power amp such as the 851W for further sonic purity.
