My comment is more general--I think in this day and age the one box solution doesn't mean a compromise for excellent sound. The birth of the outboard DAC was, at least in part, a response the the really poor analog sections of early digital gear, and an opportunity for electonics manufacturers to sell gear that didn't have moving parts and require a lot of mechanical engineering. Fast forward to today, and I believe you can have it all in one box, save on a cable and eliminate a couple of connections that need to be cleaned and maintained.
Hope this is useful.
