I pieced together my system tempoarily last night using my old Carousel CD changer to check out the SQ. I must say that while good, I was not overwhelmed. Since I plan on having only a CD/DVD combo player, I guess I need the best DAC's I can get in the food chain (990?). The lack of bass so far has surpised me, although I admit I still haven't gone through all of the set-up so I am going to hook it all up and play for a few days to see if it gets better.
