I am using the battery powered USB Select by Red Wine Audio that has been modified by them to just provide the USB output from my computer to the digital input of my DAC (it can also act as a DAC, but I would not recommend it), an Audio Mirror D1 which I highly recommend. I also use the USB Select to transfer files from my computer to my Alesis ML9600 (TRL modded) and record direct to the HD, where I can then edit and use the ML9600 as a transport to output the digital signal to the D1, or burn new CDRs (with extremely low BLER due to the mods by TRL).
The Audio Mirror is a great DAC and great value. Not as good as a Dodson I suspect, but a non-upsampling filterless design that took me by surprise and compared favorably to the Audio Note 2.1x, which is no slouch.
