There's some very good information on this thread about the 2.5 version of the Zhaolu. I would think the same could be done to the 2.0 power supply and analogue board, but you'll have to trace it out yourself.
diyAudio Forums - Zhaolu DAC - a good value DAC?
Some things that I found, and posted in that thread (so look through it completely), that helped out enormously:
- putting a pulse transformer on the digital input
- fixing the ground plane problems on the power supply board
- rewiring the analogue output section per post #303 on the thread (this was mind opening)
Enjoy,
Bob
