I am not sure whether it should be posted here by below is my [unsuccessful] experience with Volumio for Benchmark DAC1 USB and JKDAC32. It did work with two DACs from the compatibility list: iFi DSD nano and Chord 2Qute. Volumio run on Allo’s USBridge. Volumio also worked with Benchmark DAC1 USB via SPDIF, fed by Allo’s DigiOne player.
