Denafrips Terminator or Kitsune Hifi May-KTE would be good upgrade choices. Stretch some more for the Lampizator Baltic 4 (tube, can tube roll for taste) or T+A DAC200, both which sonically punches above their price points.
Other choices are Wired4Sound DAC-2v2SE, Audio-GD R7HE MK2, Bel Canto Ex1 DAC (Transparent) - all had positive reviews
