Ben, I've owned more than a dozen pieces of AA gear and still own two DDEv3s, both modified by Dusty at CIA. Sorry to give you bad news but for the most part Dusty has stopped doing repairs on AA gear since parts are no longer available. Fortunately, you can pick up a used DDEv3 for about US $300 so my advice would be to buy another one and keep the one you have for parts should the replacement fail.
BTW, I also own a Camelot Uther MkIII dac which is kind of like a DDEv3 on steroids (dual differential Burr-Brown PCM63 dacs, adjustable dither settings, analog volume control, etc) and although the Uther is clearly superior to the DDEv3 the Alchemy piece continues to provide tremendous musical satisfaction and IMO is still an excellent choice for music lovers regardless of budget or advances current technology.
Feel free to e-mail me if you have additional questions.
