Gustard dac x20 or Schiit gungnir

Hi Dear Fellows.
I’m looking for the best dac using usb input.My budget is limited to 1k dollars.Which dac could you recommend me between these two models.I actually have ead dsp 9000 pro serie 3 and I would like to make a step forward from this dac.If you have any other brand in this price range(1k)please don’t hesitate to recommend me.
Best regards and any suggestions will be very helpful!!

Cheers!
