SMSL PO-100 Pro USB Interface and DAC
I used this with a Wiim Ultra to get better sound. I learned about this from a CheapAudioMan video "$60 Hifi Hack makes WIIM Ultra Destroy Gear 3X the Price".

You take the USB Out from the Ultra, into this interface, then run a coax digital cable (or Toslink cable) to your DAC. This supposedly improves the clocking, something about the clocking gets handled by your DAC instead of the Wiim. Anyway, it seems to work.
The SMSL is small and seems to be well made. I attached it to the top of the Ultra with some blu-tack, so it effectively didn't require any rack space.
Selling this interfaced because I sold my Ultra.
Price new was $80.
