CAMBRIDGE AZUR 851C/B CD PLYER

Central to the 851C's exceptional performance is a mouth watering collection of advanced technologies, such as our high-specification digital-to-analogue convertors from respected digital processing experts Analog Devices. Together with its on-board ATF2 upsampling technology, the 851C has the ability to improve sound quality regardless of the input format. From MP3 to high res downloads, this player will showcase your music in its best possible light.

With a plethora of connectivity options, you can link up a world of digital source components to the 851C, including: TVs, streamers, digital iPhone/iPad docks and computers of all kinds to maximise their sound quality. The 851C is also capable of accepting the very highest quality music files currently available, via USB: 24-bit/96kHz (and 192kHz) for genuine studio master tape quality. So you really can get closer to the music than ever before.

For the serious audio enthusiast, the 851C also benefits from a number of ,'audiophile' features. Everyone's ears are different and you can select from three filter options which each offer a slightly different presentation.

It's this combination of our own in-house technology, multi-function flexibility and high-end ,'audiophile' components that make the 851C Cambridge Audio's most advanced digital player to date. Its ability to transform the quality of your favourite music, regardless of format, means the 851C is destined to become the heart of your digital music system.

Particular attention has also been paid to the 851C's casework, which combines massive structural rigidity, careful damping and control of acoustic resonance. Both inside and out, the 851C and matching 851A have all the hallmarks of high-end thoroughbreds.
