Sorry, two things I need to add:I have the Gustard X20 and am running DSD256 from J.River and it sounds great. What would I be getting by adding the Singxer and outputting DSD512?
1. My experience of DSD512 is via Roon on a Linux based server - not JRiver on a Windows OS.
2. The Singxer probably has a better USB implementation than the X20, so USB-i2s (shortest cable possible to DAC) might give you audible benefits regardless of the sample rate you adopt. Others more knowledgeable on the hardware differences, respective clocks, etc., may wish to chime in and either confirm this or flame me!
