Better desktop DAC

Hi, I am looking for a better DAC in my home office system, to replace the Topping e30ii. It must be able to playback pure / direct DSD. The sound must be clearly better. Preferably a portable DAC, not a huge box. I am streaming through an ethernet-connected laptop and experience no problems, but may consider a new streaming solution too. Total budget; low to medium. Buying used is OK, as long as the DAC can handle DSD.

Suggestions welcome!
