Unfortunately, knowing how all my headphones behave with the desktop system (I have them of various types, dynamic and planar, with high and low efficiency/impedance), when I tried to connect them to the DX300 (but I think this applies to any other DAP), I feel a fairly evident decrease in performance.
Instead with the IEMs the DX300 brings out a musicality and a detail that no full-size headphone has ever given me; not to mention the low range, truly impressive in terms of cleanliness and depth.
