among standalone dacs, i would suggest you try a chord qutest or 2qute - qutest around $1400 used, 2qute at about $800 of that amount but the sound is very very close - they also benefit from a suitable filtered or linear power supply ($75-150 additional)
both will give as much airiness in soundstage and detailed midrange among dacs in this price range, and much better than the internal node n130 internal dac, which is smooth but lacks incisiveness
the topping d90 and rme adi2 provide a similar tonality to the chords with a crisp clear sound, but without the excellent imaging and as much clarity of transients
