I too would get the Cary 306. I have the 306 Pro. I had a Naim CDX2 and XPSII but then a I borrowed a friend's 306 for a month. After 3 weeks with it, I sold the Naim gear on Audiogon and purchased the 306 Pro. At the time, I had no idea I would be using it more as a DAC for my computer set up, but it is just as satisfying. I am 95% sure the 306 has a digital in too...
Good luck!
