just incase you haven't gone down the bleeding obvious route, here's the manual.

Ladies and Gentlemen I figured it out....

This thing im told is real picky about voltages.. any one of those things could have caused just enough drop to not make it work.
and here is where you might check first .. the DAC overheats... you have to take the sink off.. reflow the solder, re paste it. put the sink back on.
