Sorry for the poor photo but this will show you how mine looks with the upgraded caps.
C19 is 1000uf Pana FC.
C21 is 150uf Pana FC.
You can use your 470uf at C19. C21 should be smaller.
C9 is Vishay mkp1837 0.1uf. This was the best i found after trying twelve different caps here. Big ones don't work properly and generally mess up the sound, sometimes in a big way.
C9 is in my opinion one of the most important caps on the board. This also the only surface mount that i removed.
C16,17,20 and 25 are Oscon 150uf 16v. Probably enough Oscons.
C3,C18 are 220uf Samwha caps(gold), but any decent quality cap suitable for purpose would perhaps do.
C8,11,12,13 are 3.3uf Tants.
All lytics are bypassed by 0.1uf film caps.
I think blue Vishays are preferable to Wima, anywhere on this pcb.
This DAC works very well. Hope this is helpful.
