I soldered the jumper back and now it's OK, but sometimes there are still some instabilities. Nevertheless the day plays fine.

Hi Quanghao,
My version-1 DAC still needs the modifications to the shunt regulators, and I don't have the skills for such precise soldering.
So I would like to send the DAC to you in Vietnam. Could you please advise which address is correct -

- Dong Da District (I received the ver 1 DAC from this address)
or
- Ba Dinh District (I recieved the LL1684 PCB from this address)
or
- Hoang Mai District (as listed in the User Manual)

Thanks.
