"A premium music streamer with the performance to match"  What Hi-Fi Award Winner 2017. Product of the Year.

Putting sound quality first

As Cambridge's range-topping network music payer you'd expect the Azur 851N to be pretty special under the lid, and that's exactly what it is! The highest quality sound comes from the use of audiophile quality components and tireless research and testing. As an 8-series design, the 851N uses a substantial toroidal power transformer at its centre. This enables clean, effortless power to be supplied to the other components, allowing them to give their best. High quality Analogue Devices AD1955 DACs (Digital to Analogue Convertors) are configured in dual-mono mode, ensuring maximum channel separation and precise sound-staging.

Fully equipped for High Resolution Audio
At the heart of the 851N is a brand new Zander processor that facilitates 24-bit/192kHz file high resolution streaming from most methods - even Wi-Fi. On top of this, the 851N is compatible with a huge range of high resolution files, including ALAC, WAV, FLAC, AIFF, WMA, MP3, AAC, HE AAC, AAC+ and OGG Vorbis. The USB audio input also enables streaming of up to 24-bit/192kHz audio and even supports DSD streams from your computer. Originally designed for SACD players, DSD (Direct Stream Digital) encoded music files offer the same detailed, transparent sound as other high resolution file formats, giving you even greater choice of listening.

AFT2 Up-Sampling for the ultimate detail and least jitter
The Cambridge 851N improves sound quality still further with an Anagram Technologies AFT2 24 bit/384 kHz up-sampling circuit. ATF (Adaptive Time Filtering) up-sampling 'stretches' the music to give the highest resolution possible. Up-sampling sound gives a smoother, more relaxed sound quality with added detail. You'll also notice enhanced depth of sound and a more natural quality without the "edge" that can afflict digital music. You'll hear every detail, including every deep breath, squeaky chair and flutter of sheet music; in short, it's like being there for real! AFT2 even aids native 24-bit/192kHz recordings with a faster sampling rate for even less jitter.

Connect to Internet radio and Spotify Connect
In addition to supporting over 20,000, easy to access Internet radio stations, the Azur 851N is also compatible with the most popular music streaming services. Spotify is the world's most popular streaming service and the Azur 851N has Spotify Connect integrated into it. If you subscribe to Spotify Premium, you can control the Cambridge with the powerful Spotify Connect app on your phone or tablet. Should you prefer other music services, the 851N also supports Napster, BBC iPlayer for radio, Aupeo! Pandora and Rhapsody.

AirPlay and optional Bluetooth
In addition to comprehensive streaming capabilities over LAN, Wi-Fi and USB, the 851N is also compatible with Apple's AirPlay streaming. Use it with your iPhone, iPad PC or Mac and wireless stream your iTunes library or other compatible music services. Connect up the optional BT100 dongle and you'll be able to stream your music from any smartphone, tablet or other device with Bluetooth built-in.

Built-in digital pre-amp - just add active speakers!
If you're seeking quality hi-fi from a minimal system then the built-in digital pre-amp will appeal. Simply add active speakers via the digital or analogue outputs and you'll be able to control the volume and balance via the Azur 851N.

Fully connected, including XLR balanced sockets and 5 USBs
When it comes to connectivity the 851N lives up to its 8-series 'reference' billing. The highlight is the fitment of XLR balanced sockets. When used with a compatible amplifier, such as the matching Cambridge Audio 851A, these connections give the ultimate link possible, with greatly improved resistance to interference. There are also AES/EBU balanced digital input/output sockets for the ultimate digital connections. Added to this there are no fewer than five USB interfaces! The front-mounted socket is ideal for connecting temporary devices such as USB media sticks. At the back, three interfaces take care of more permanently connected media devices plus the optional Bluetooth dongle port. A Type B asynchronous USB input is provided for the direct connection of your PC or Mac. This makes the ideal connection for hooking up your computer as it will effectively 'control' the PC's output for the best sound quality possible. This greatly reduces jitter and gives the highest quality sound possible from your computer audio. Finally, both optical and coaxial digital sockets are provided for both inputs (x2) and outputs. This lets you connect up other digital components and take advantage of the quality DAC built into the 851N.

Intuitive app interface and colour display
With a free Apple/Android app you have effortless control over the radio stations with the comfort of your iPhone/iPod Touch/iPad or Android device. The app also seamlessly manages all your streaming content and is, in effect, a very user friendly way of bringing together and controlling all your digital sources. Boasting a new colour screen, it's now possible to display album art on the player. This makes it a pleasure to browse for albums and artists by whichever control system you use.

Full metal casing with extensive damping
Using a full metal casing, with rounded edges, doesn't just look and feel good, it helps the sound, too. The case is rigid and well damped, meaning that it won't resonate unhelpfully. The thick aluminium front panel looks the part and also acts as a shield against electrical interference from sources such as dimmers and RF devices. All these details combine to create a network player that not only looks stylish but also offers exceptional resistance to both mechanical and electrical interference.

A first-rate performer in every respect, the flagship Cambridge Azur 851N network player is the audiophile's choice of streamer.

Rated 5 out of 5 by from Equipped with excellent dac This streamer is equipped with extremely high quality DAC. The upsampling of lower music sources like mp3 is absolutely fenomenal. High resolution files sound heavenly good. It is also very easy to use. In my opinion below 2k mark there is nothing out there that's sounds better. Every time I listen to this thing it puts great smile on my face. Highly recommended.

Rated 4 out of 5 by from Almost Great ...... but not quite I bought the 851N as a replacement for my aging Squeezebox streamer and in many ways I'm glad I did, the improvement in sound is fantastic as I now have a streamer that works well with the rest of my reasonably good system. However, sound quality is only one part of the reason people buy a streamer - the other is controllability and convenience. I'm afraid the Cambridge Connect app is not up to the task of providing the seamless usability that we've become used to in recent years, it also looks a bit windows 95. The free 3rd party app I used with my Squeezebox was leaps and bounds better. There are other 3rd party apps available of course but none I've tried are brilliant. I don't regret buying the 851N, it does sound the business but I do feel the app lets it down a lot. I also wanted to listen to BBC iplayer radio using the streamer but this has not been possible due to reasons beyond the control of Cambridge, so not their fault. So why does the Richer Sounds blurb still mention the ability to use BBC iplayer radio? This information should have been removed a year ago. Overall, a great piece of hardware let down by a half baked app.

Rated 5 out of 5 by from Excellent product. Just upgraded to the 851n from the original Stream Magic 6, and to say I am blown away is an understatement. I've had a couple of days to really listen to everything from CD quality to Hi Res downloads of 96/24 and 192/24 and lets just say it's truely phenomenal. Add to the above the build and great colour screen and you've got everything. If your looking for excellence then don't bother with anything else just go for the Cambridge 851n.

Rated 5 out of 5 by from Incredible Product I've been very impressed by the 851A/C combination that I've had for 3 years so I was already sold on the sound of the 851N, which shares the same digital signal processing as the 851C. The key requirement for me was the ability to read multiple file types, particularly FLAC, ALAC, WAV, and MP3's, irrespective of sample frequency and bit depth - My aim was to consolidate disparate folders, specifically my i-tunes library, CD rips, digitized vinyl, and 24/96 FLAC files into one library located on a portable hard drive connected via USB. The 851N reads everything I've thrown at it so I finally have a single integrated digital music library, arranged by artist, without having to convert files. The unit was simple to set up. It found the WiFi quickly, did a firmware upgrade and then it was away. Inputting album art has been the only pain as it does not recognize art embedded in the tags, thus a jpg or png image has to be placed in each album folder to get art on the front display

Rated 4 out of 5 by from Sounds Good and Solid Build The 851N already sounds good after 20 hours use. Recommended 36 hours before 'burn in' so only half way. It has 'bullet proof' build and more connectivity than you would normally need. It has more presence and 'slam' than the CXN it replaces. The CXN is impressive but the 851N has already demonstrated why it is worth the difference in cost. Especially at £200 less than list price!!!

Rated 5 out of 5 by from CDs are dead Originally I bought a CXN streamer to go with my new Roksan Kandy K3. It sounded brilliant and I was more than satisfied.But now I realised just how good Cambridge streamers were and decided to upgrade to the 851N. It is a big step up from the already good CXN. It is neutral sounding,in that it doesn't favour any particular frequency and is superbly rich and detailed. I have ripped all my cds and put the on a NAS drive. I now only buy cd quality or higher downloads as the difference on the Cambridge is quite noticeable. Overall the 851N sounds beautiful, never tiring but always exciting. Highly recommended.
