Yes the RDC-7 has a Digital out (coax and tosloink) to go to an outboard processor or DAC. What kind of Audio Pre are you concidering?
My main concern was to get rid of some of my components, I had a seperate AV Preamp, Separate Digital Processor, DAC, etc. This unit has combined the Pre and the Processor. I am still testing with my DAC to determine if I want to get rid of it too. I have been listening to the RDC-7 DAC's and I enjoy them quite a lot, the only thing that is different, as stated earlier is the "tube bloom" in the midrange.
