Product Highlights

    Santa came early this year and his red velvet bag brought you Cambridge Audio’s Azur 851C Flagship Upsampling DAC, CD player & Preamplifier. Let your friends and family marvel at the cornerstone of your digital hub with advanced technology and audiophile grade components designed to deliver perfect sound that’s free from vibration, jitter and unwanted distortion. Connect to just about anything digital, no matter where your music comes from the 851C will filter everything you send it through a 2nd generation proprietary ATF upsampling technology that converts everything to 24bit/384kHz hi–res quality. 3 digital filters include linear, minimum and steep for custom sound made just for you. Premium XLR and RCA outputs provide connectivity to a multitude of other sources including the perfectly compatible 851A integrated amplifier, or use the 851C as a digital pre–amplifier and connect to the 851W power amplifier or pair of active speakers. Optical and co–axial digital inputs and outputs, and an asynchronous USB audio input rounds out the first class features of the 851C.

    Flagship Upsampling DAC, CD Player & Preamplifier

    Our finest CD player and DAC, the 851C uses our extensive digital knowledge to become the cornerstone of your digital hub. No matter the source of your digital music, twin DACs in dual differential mode and 2nd generation Adaptive Time Filtering make the music sound as the original artist intended – extraordinary.

    Sound Perfection

    The 851C uses audiophile grade components throughout and incorporates our most advanced technologies to ensure it plays music perfectly. Your discs are spun on our own audio–only transport and coupled with our S3 servo to give error–free data retrieval and jitter minimisation. Our ultra–rigid metal construction also ensures components are isolated and free from vibration.

    All data is then 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. The upsampled music 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 to process data. The result is lifelike stereo imaging where instruments can be heard in specific parts of your room with uncanny accuracy.

    Digital Pre–Amplifier

    With premium XLR and RCA outputs you can then connect the 851C to the perfectly compatible 851A integrated amplifier with other sources. The 851C also has a digital volume stage built in so it can be used as a pure pre–amplifier a?? just connect it straight into our 851W power amplifier or a pair of active speakers for further sonic benefits.

    Digital Filters

    We built the 851C with three selectable filters, linear, minimum and steep, this allows you to choose the type of sound that suits your ideal listening preferences.

    Connections And Flexibility

    The 851C isn’t just built for playback of CDs; we wanted to make the most of its ATF upsampling and superb DACs, so it’s a complete digital hub which can connect to almost anything digital. It’s got optical and co–axial digital in and outputs plus an asynchronous USB audio input. So you can connect up TVs, streamers, PCs, MACs and more, and everything will be upsampled to amazing hi–res quality.
