Another vote for the Schitt Modius. It's simple, measures well, and it works. It also has the ability to drive both single ended and balanced outputs independently.
The Khadas Tone Board 2 is interesting assuming they do manage to release upgradable firmware to correct the filter error, you like the form factor, and are willing to spend the money on extra adapters for balanced cables.
The Soncoz LA-QXD1 thread has too many premature failure reports, which considering the likely smaller sales volume vs larger company DACs, rules it out for me.
