Ah, sort of like this? Quick question for @Quadman : What method did you use to remove the coax tower? I'm thinking heat gun but if there is a better desoldering method I am all ears. Since getting the Singxer I just threw the DIYinHK board away. That thing was terribly unstable. The singxer has its quirks too. Just for reference I have the gustard connected by a Monoprice sleeved 18awg 1 foot length HDMI cable. It is insanely stiff and I had to form it before connecting the Singxer and Gustard. Basic method is this: -Install SIngxer drivers -Use SIngxer XMOS dfupdate to update firmware to v 2.22 -Uninstall Singxer drivers (limited to DSD256 via DoP) -Install HoloAudio signed XMOS drivers for kitsune Spring DAC with SU-1 connected -Make sure your SU-1 is NOT plugged into a USB 3.0 SS port (took a while for me to realize this goof) -Enjoy I still have to unplug and replug the Singxer USB occasionally or else the left channel is pure static in DSD mode on a rare occasion. Not sure if that is just my setup though.
