The best digital setups that I have heard have all been separates, except for the Exemplar Denon 2900 which is an oustanding one box modded player. In general I don't buy the less is more argument in this case because it does not ring true with my experience. I'd say it has to do more with the overall design of the components than the simplicity of the path. Using a separate DAC and transport is more expensive and real estate intensive, but each component can be tailored more precisely to its needs.
That said, it's very nice to have a great one box player for the simplicity and I wish they all were!
