Overview

Cambridge Audios 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.
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.
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.
