I briefly used USB from a Mini to an Oppo 205 with balanced analog to a pair of Parasound JC 1 monoblocks. Then I switched to USB from the Mini to an Ayre QB-9 DSD DAC with balanced analog through an Ayre K-5xeMP preamp to the JC 1s. A big jump in sound quality came with replacing the Oppo with the Ayre DAC and preamp. I added an ultraRendu with LPS 1.2 that sends USB to the Ayre DAC on the hunch that Roon finds devices connected to the Ethernet more reliably. Roon always finds the ultraRendu, but often didn’t find the Ayre DAC.
