FX-AUDIO FX-D03J Input: USB Output: Optical, Coaxial Purchased about a year and a half ago, used 1-2 times a week (alternating with other DACs), and is fully functional. Includes all accessories (instruction manual and USB cable), but no original box. If desired, I can include a separately purchased USB cable (approx. 50cm or 1m). Please comment if you'd like one.
