Sound Perfection

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 Preamp

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.
