SweetVinyl SugarCube using external DAC

I am using a SugarCube SC-1 mini with an external format converter (Singxer F1 USB to S/PDIF) so I can record the 32 bits/ 192 kHz output on my computer. I also use the SC-1 with other external DACs. I am experiencing some issues and I would like to know if anyone else has experience with external DACs with any of the SugarCubes.
