I once had a Bel Canto Dac1, and its sound was fantastic, far better than an Apple TV's analog outputs. I'd say that a Dac2 is a very safe bet to be noticeably better than no dac at all. It'll also hold its resale value.
FYI, the Bel Canto is a bit on the smooth side of things, which is usually a good fit with low-grade digital sources.
