The Bryston BDP-3 is also worth a look. Software interface is a bit spartan but it works and the product support is good and their SQ and right up there with the best.
If you do consider Roon , which gets you a super nice interface on your iPAD, I would also look at Small Green Computer (SGC) as previously suggested. It just takes some knowledge and patience to get it all dial in but you wont be dissappointed.
