Azur 851C Upsampling DAC, CD Player and Digital Pre-amplifier

 

The heart of your digital music system

 

Our new 851C is a staggeringly complex creation but one with a simple mission: to make your digitally stored music sound sublime. Its a high-end CD player, a state-of-the-art DAC and digital preamp in one highly accomplished package. The 851C has been designed to operate at the very heart of your digital music system, offering incredible functionality and performance. As a high-end solution to the demands of todays multi-format music lover, the 851C is truly capable of enhancing any digital audio that passes through its sophisticated electronics.

 

Central to the 851Cs 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.

 

Its this combination of our own in-house technology, multi-function flexibility and high-end audiophile components that make the 851C Cambridge Audios 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 851Cs 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.

 

 

A trio of talents…

 

The 851C as a high-end DAC

Perhaps its most significant additional function is that of a fully fledged, high-resolution, audiophile DAC. Used in this way, its capable of breathing new life into audio produced by everyday digital components by utilising its state-of-the-art internal convertors to bring sparkling clarity and detail to audio streams.

 

Rather than investing in a separate stand alone DAC, any gadget with a digital audio output - from TVs to computers and digitally docked iPod/iPhone/iPad devices can benefit from 851Cs highly advanced digital audio processing technology.

 

 

A number of external devices can be attached to your 851C thanks to two S/PDIF (coaxial) inputs, two Toslink (optical) inputs and, for truly high-performance sound quality, a 24-bit USB input capable of up to 192kHz resolution. The latter enables you to experience true studio master quality from the highest resolution music files available.

 

 

The 851C as a high-end CD player

Quite simply, the 851C is an outstanding CD player in its own right. It incorporates numerous technologies, including the aforementioned Analog Devices DAC, the ATF2™ upsampling process and balanced outputs. But at a more fundamental level, our engineers have created a specific, custom-designed CD-only servo mechanism which has the ability to retrieve the maximum amount of information from 16-bit CD.

 

A Cambridge Audio-developed transport complements the servo electronics perfectly, adding an additional audiophile touch to this critical part of the reproduction chain.

 

 

The 851C as a digital pre-amplifier

Further adding to the flexibility of this hugely versatile source component, is its role as a digital pre-amp. With consumers increasingly using digital audio sources (computers, streamers and digital iPhone docks, etc.) the 851C can be used to control volume and balance levels when connected directly to a power amp or active speakers. This clever feature, processed completely using digital technology, facilitates the simplest of audio replay systems and offers amazing flexibility. The function is operated using Cambridge Audios proprietary DSP (Digital Signal Processor) and gives the highest quality of digital volume control, as opposed to analogue attenuation or digital bit reduction.
