I believe the smaller caps are the power supply decoupling caps and are required for stability. The larger caps are connected to pin 7 of the chip, and it is my understanding that they can be removed. It will change the sound quality, but the chip will still function.
I bought mine from "SHS IC Store" for 6.62€. Already asked for refund...
Fortunately I have access to some nice "toys"/tools at work so I could take the module out during lunch time. All caps on my board are the same. Looked at them with microscope at work...
Found HuaXinHuiDianZi Store, same price (6.64€). But had to search quite a bit to find it... From the pictures they have, it's easy to see the difference on the caps size. (their ranking is also quite good). Already bought one not to loose more time. If I have a replacement working, I'll make a second DAC... already have 4 more pcb's, cap's, resistors, etc...
