Description

Cambridge Audio 851C Upsampling DAC, CD Player, and Preamp with USB (Silver)
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.
All of these audiophile internals are powered by a large toroidal transformer for the best delivery of a high quality and consistent signal with low noise and buzz levels.
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 – 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
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.
This is a refurbished previously owned and loved Cambridge product which has been expertly repaired. All products come complete with original accessories.

If you're unhappy with your purchase, please let us know. Unless faulty, we'd like this to be within 30 days of purchase and It's important that any unwanted item, unless faulty, is returned in a re-saleable condition. We'd expect this to mean that you've kept all original packaging and labels, and that it's undamaged and unused.
We'll require an explanation for the return (defective, damaged, etc). Don't be surprised if we ask you some pretty detailed questions about the reason for your return. Hearing first-hand what our customers are experiencing will enable us to provide you with the best possible service.
