820uf is connected to which pin of opamp....? and if i see correctly it is connected to rca output and 2 smd resistors are connected trough via ...to gnd?
If this 2 resistors are 102 than this is 1kohm that is too low.

The 820 uF is across pin 4 and 8. I don't know why this is even something to doubt at all. It is vary common to run a larger value electrolytic next to the DIP8 socket for a filter near the source. The audio signal is all surface mount. The AKM outputs a dif output and the op amp takes it in. They should run a coupler cap and it might be the two 100pf and the 390pf might be the output coupler but I need to trace it better to know for sure. They are quite small and I don't think I will gain much by going to polystyrene but I want to practice my micro soldering anyhow.
The DAC works fine and it really sounds nice so far.
I dont know what the you ruined your DAC means. It is a low cost board and I'm having a little fun with it. After a few mods I compare it to the $400 DAC and see if its getting closer. It has room a lot of different op amps and I'm going to stick a desecrate or two in it. The AKM so far is a nice sound unit and I like it a bit better than the ESS.
I'm working on new speakers and building a Amplabs lateral amp for a second system. My old Focal 7N driver will finally get to be used and I have high hopes for the Lateral FET amp.
