For sale is a like-new Gustard U12 USB to SPDIF converter. Will also output IIS via HDMI. pCM support up to 384k and DSD up to 128. Rivals USB converters costing significantly more. I own 2 but no longer need this 2nd one. It never actually got used so is still in like-new condition. This is the black faceplate version for 120v.
