Audio-gd DI-20 is not a Reclocker but a DDC and it will improve the sound of your DAC a LOT.
I'm re-reading this thread and came across this post, which led me to researching the Audio-GD DI-20. I didn't know Audio-GD made a product like this. Based on initial review, I would say that this DI-20 could be much better than the stock Singxer SU-6. It already has a built in linear power supply, uses the Amanero USB board, and has options for Accusilicon 90/98M clocks (which isn't that much more in cost). I have direct experience using the Accusilicon clocks and they are abosutely excellent. The double speed 90/98 clocks will likely be more accurate that standard 45/49 clocks.
The HE version looks to be much better with a much beefier power supply. This one could be sleeper!
