A little background info…

Our finest CD player and DAC, the 851C use 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 minimization. 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 the internals are powered by a large toroidal transformer for the best delivery of high quality and consistent signal with low noise and buzz levels.
