  • ATF2 audio up-sampling to 24-bit/384kHz
  • Weight: 7.5kg (16.5lbs)
  • Twin Analog Devices AD1955 24 bit DACs
Model: 851D

Draw every last detail from digitally stored music!
 With a comprehensive range of connections and high-end component designed to draw the best from any digital source, it delivers your digital music in upsampled, stunning quality. The 851D is the last word in high-end digital-analogue conversion.

ATF2 upsampling – All stereo sources can be upsampled to 24-bit/384kHz, kept jitter-free by proprietary, second generation ATF Adaptive Time Filtering algorithms co-developed with Anagram Technologies of Switzerland.

Digital inputs – Six digital inputs (including coaxial, Toslink optical, BNC coaxial and AES/EBU), plus asynchronous USB and optional Bluetooth wireless ensure that the widest possible range of digital sources are supported, with input source quality of up to 24-bit/192kHz.

All-metal chassis – Combines structural rigidity, careful damping and control of acoustic resonance.ritical low level gain stages, these offer far improved stereo separation and imaging – unheard of at this price point
