Well, I have this Starting Point Systems NOS DAC board, which I powered with a 12-Volt battery.  Here's a link to a current eBay listing:

Mine is slightly different--I mounted the board to small panel just so I could use it more easily, and I believe the previous owner upgraded the two big capacitors.

$40, or if you have something to trade, maybe a set of isolation points or other interesting tweak.  No cables, though.

Bump!
Would trade for
  --isolation cones
  --speaker wire--need not have terminations
  --aluminum or steel chassis/project boxes
