    SOUND PURITY

    We built the 851D using all of our hi-fi experience and the highest grade of components throughout to ensure it delivers the best sound in its class. You can connect up virtually any source and then let the 851D bring it to life. All data is 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 your music sounds amazing. Read more on our proprietary ATF upsampling technology here.

    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, low noise and buzz levels, and huge power reserves.

    CONNECTIVITY

    We’ve built the 851D to connect with as many digital sources as possible. There are digital TOSLINK, S/PDIF, BNC and AES/EBU inputs, while if you add a BT100 Bluetooth dongle you can pair with compatible devices for wireless Bluetooth streaming. For your PC there’s an asynchronous USB audio input with a dedicated driver, allowing you to bypass the PC’s poor audio path. All inputs are upsampled to 24-bit/384kHz meaning you can connect up a world of digital source components including TVs, media streamers, smartphone docks and computers, and enjoy it all in amazing hi-res quality.

    DIGITAL PRE-AMPLIFIER

    With premium XLR and RCA outputs you can then connect the 851D to the perfectly compatible 851A integrated amplifier with other sources. The 851D 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 851D with three selectable filters, linear, minimum and steep, this allows you to choose the type of sound that suits your ideal listening preferences.
