I already receive yours opams and clock. Capacitors i bought in China (Elna Slimic II, Murdorf, Vishay).
I sand you photo of upgrade process.

DAC_1 original,
DAC_2 desoldering
DAC_3 modification result

It is difficult compare if is not possible do A-B test. But I feel upgrade bring significant improvement in clarity
and naturality. Also the bass are better. Thanks for your help.
