More than just a DAC, the Cambridge Audio 851D is a digital pre-amplifier that's at the heart of your digital system.

Complete digital pre-amp

Marking the Cambridge Audio 851D out from its DAC rivals is the unmatched flexibility. Take a deep breath and take in the following: six digital inputs including a professional standard AES/EBU, rare BNC, twin optical, plus two more inputs offering the option of coaxial or optical. There is also an asynchronous USB link that supports high-resolution audio files up to 192kHz, making the 851D ideal for high resolution music playback from your computer.

It's also a DAC
In terms of connecting the DAC to your amp, take your pick from optical or coaxial digital and RCA or XLR analogue. Throw in a control bus link, RS232 socket and trigger out for multi-room system control and it's hard to see how the 851D could be any better equipped. With the supplied remote control offering a switchable volume control there may be no need to add a pre-amp at all*. Just add a power amp or active speakers and you're all set to go.

Bluetooth connectivity
Supplied with the Cambridge Audio BT100 Bluetooth dongle, the 851D will accommodate Bluetooth music transfers from your smartphone, tablet, laptop or other compatible devices. Although not quite the quality of other streaming sources, it's handy to have when playing background music. Thanks to A2DP plus aptX support, the quality is as good as is possible using Bluetooth.

Superior components
At the heart of the 851D are two Analogue Devices AD1955 24-bit DACs in dual differential formation. Each DAC handles just one channel for excellent stereo imaging, operating fully in differential mode for exceptionally low distortion and noise. What you hear is an exceptionally unforced, natural sound quality with instruments and vocals 'breathing' with emotion and depth.

ATF2 audio upsampling
The high quality DACs are complemented by a new Anagram Technologies ATF2 24 bit/384 kHz up-sampling circuit. Up-sampling lower resolution sources 'stretches' them to give the highest resolution possible. It also aids standard 24-bit/192kHz recordings with a faster sampling rate for less jitter. You'll hear a smoother, more relaxed sound with added detail and enhanced depth, without the 'edge' that can afflict digital music

Tailored sound
As we all prefer slightly different nuances of sound quality, the 851D comes with Cambridge Audio's triple filter system. Select from Linear Phase, Minimal Phase or Steep modes and you can subtly alter the sound quality. You might even find certain types of music sound better with a particular filter engaged.

Full metal casing
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, so 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. Together the 851D not only looks stylish but also offers exceptional resistance to both mechanical and electrical interference.

Unequivocally the best DAC we've ever sold, with a level of connectivity that also puts it in a class of its own, the Cambridge Audio 851D is the ultimate heart of your digital system.

*Conventional pre-amplifier required if connecting analogue sources to your system; such as turntable, tuner or cassette deck plus CD players without digital output.

CAMBRIDGE AUDIO AZUR 851D is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Amazing DAC This is a truly high end piece of equipment which oozes quality. The build quality is amazing with a solid feel and full metal casework, and the sound is extremely clean and detailed. This DAC is only worth purchasing if the rest of your other kit is up to the same quality, otherwise it's true qualities will go unnoticed. Excellent top of the line product, and I'm very pleased with it.

Rated 5 out of 5 by from Excellent comprehensive DAC The 851D arrived exactly when stated and after I took it out of the box, I placed it on my Hi Fi rack and left it for two days to allow it to acclimatize to the warmer air in the house. The unit had felt quite cold when I removed it from the box straight after delivery, and I didn't want to power it up with the risk of any condensation on the circuit boards. I hooked it up to several digital sources including a Sansui DAB/FM/Internet tuner (optical connection) and a Pioneer multi-format disc player (co-ax connection). The manual was easy to follow and I decided to 'dis' the variable pre-amp volume control part of the unit, and keep the analog output 'fixed' and fed the XLR balanced output into my 851E pre-amp. It all worked first time. Very often things don't work first time with some kit due to misreading or misinterpreting the manual, but with the 851D, it was a doddle. The sound quality of the 851D feeding the 851E and then into the 651W power amp is beyond reproach.

Rated 5 out of 5 by from Amazing I would have never thought that a DAC could make such a difference The 851D is splendid unit beautifully engineered and it sounds so so good I would recommend that you have a listen to this unit before you buy a cheaper one
