It does both very well, is very small so easy to carry around looks great. Feels very nicely made and most importantly, the sound quality is excellent. Really really excellent device and I am very happy with it.
Review: Nice headphone amp and DAC - I purchased this headphone amp and DAC for use in the large shared office, and I like that it is small and fits nicely into both my laptop bag and locker.
