The Pi Dac utilises several unique applications in digital playback. Utilising the latest in advanced clock technology with a FIFO (first in first out) reclocker, the clock signal is stripped and reframed in a grossly more accurate time domain. In addition, the latest ESS chip has been programed with modest and organic sounding filters. This results in the organic sound of NOS DACs but with the greater low level detail of modern chip sets.
