If you have a DAC already and you compare listening via the ipod analog out vs. docking it in the Wadia and sending a SPDIF signal to your DAC it will improve it a lot. I think it sounds even better than my CD transport feeding my DAC.
Keep in mind if you have an older Ipod then it doesn't work that well and possibly not at all.
