For sale is my Audio-GD DAC-19 DSP1 (2010), it works and sounds fantastic. I am switching over to a smaller unit and claiming some of my desk space back. I am the 2nd owner and have taken very good care of it, unfortunately the previous owner did not pack it correctly and it got banged around during shipping to me. There are some scuffs, scratches and a gouge on the dial as shown in the pictures, this is purely cosmetic and does not affect the operation of the unit.
I have changed out the blindingly bright blue LED with a less bright and less offensive amber colored LED. It comes with the power cable and premium ACSS cables. This unit has v7 firmware installed, but I can install v5 if so desired, v5 does have imbalance issues in NOS mode though. As far as I know, the USB module is an older one and can only support 48/24 max, the COAX which is what I use supports 96/24 max.
