What exactly would you like to do? Simply get digital audio out to a digital amp?
Currently I have an Adcom preamp, Adcom GFA555,and Definitive Technology BP-10 speakers. My pre is the weakest link at the moment due to only having rca ins. I will be upgrading in the near future. I am eyeballing the Audio Engine dac and the streamer II.
