The Wadia does not itself do any digital to analog conversion.
The Wadia 170i and 171i docks bypass the iPod's own built in DAC (analog being what you get when using almost any other iPod dock) and takes the digital signal from the iPod and outputs that digital signal via coax digital out (170i) or coax or Toslink for the 171i.
So you need a DAC to convert the signal to analog. Or just use a Sunfire preamp.
