Beautiful sound

You can stream virtually any file to the 851N and its internal engine will then bring it to life. Firstly, all tracks are put through our 2nd generation Adaptive Time Filtering that upsamples everything to 24bit/384kHz hi-res quality, no matter the original source. As a result, jitter is almost completely absent, and the music sounds amazing. Read more on our proprietary ATF upsampling technology here.

The upsampled data then passes through Twin Analog Devices DACs (very high-end digital to analogue converters) which are implemented in a dual differential configuration meaning each channel has its own DAC. The result is lifelike stereo imaging where instruments can be heard in specific parts of your room with uncanny accuracy.

All of these audiophile internals are powered by a large toroidal transformer and wrapped in rigid metal casework for the best delivery of a high quality and consistent signal with low noise and buzz levels.

Digital pre-amp

Not just a great network player the 851N is also an outstanding digital pre-amp that can be connected directly to dedicated power amplifiers as well traditional integrated amps. Keeping the signal digital to the last moment makes it less susceptible to analogue deterioration, while a 32-bit SHARC DSP controls the volume output; by keeping the entire signal digital the best possible sound is achieved, even at very low volume levels.

Ultra connectivity

The 851N takes almost any digital file from virtually any source and renders it to the highest possible standard meaning any digital audio source can be enjoyed as part of your hi-fi set up. Its wireless options include NAS Drive / UPnP compatibility, internet radio, Spotify Connect, and Apple Airplay. Add an optional BT100 Bluetooth dongle and any Bluetooth device can be connected also.

Digital source components such as TVs, smartphones, PCs or MACs can connect via optical, co-axial, AES/EBU and asynchronous USB Audio digital inputs. Music files in all the popular formats are supported, from MP3, through to FLAC/Apple Lossless, DSD64 and WAV 16-24 bit master files.

The 851N will play anything you want and thanks to its huge processing power and effortless functionality from our award winning StreamMagic platform, it’s a seamless listener experience.

This is a serious improvement on the StreamMagic 6. A lot easier to handle. Owner of SONOS and BLUESOUND streamers, the 851N has a much better DAC, I consider it as good as my OPPO-HA1. The 851N allows easy adding hi-res music to my normal CD collection. Suggestions: 1) Add converting possibilities to the 851C CD player, then we really have an integrated solution... 2) Support for QOBUZ would be great (source for classical music) ;-) BTW my age (57) is completely ignored in the How-Old-Are-You?

The Azur 851N is my first Cambridge audio product I have purchased and I was pleasantly surprised by the quality. Not only does it sound fantastic, but also the build quality is awesome. The product is very well designed, it worked straight out of the box, without any installation problems. I'am going to have a lot of fun with this one!

1 - No "SEARCH" feature, it's very bad. It's a waste of time to find your albums in hard disc. The simplest devices have that this feature too. 2 - Device is constantly restarting. 3 - No a-z index for androit. 4 - And finally, you can not get the songs forward. In short, the software sucks.

Propriétaire de la série 851 (ampli et pré-amp), je me suis décidé à acheter le Streamer 851 et je ne suis pas déçu. Pour information, l'ensemble de mon système est connecté via des câbles XLR, complété par des enceintes PMC Twenty24. La qualité perçue et, surtout, la qualité audio vous fait sentir entrer dans le High-end et ce qui me frappe c'est la transparence de la combinaison du système. Chaque jour est un plaisir d'écoute et m'asseoir dans le canapé pour faire une pose musicale est un régal. Je regrette seulement une seule chose : le manque d'ouverture vers TIDAL et QOBUZ. Plus particulièrement ce dernier qui pourrait véritablement encore mieux permettre de jouir de mon installation. A quand une mise à jour logicielle?

I added the Azur 851N Network Player to my audio system and it sounds alive at last. The 851N replaced my Jolida Glass FX DAC, and my ASUS Xonar Essence STX soundcard. I have a Jolida JD323CRC Integrated Amp in "by-pass Mode" utilizing the amp-preamp feature. Amazing sound.
