AN DAC upgrade (?)

Digital Drive

Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

Hi all. Am looking at an Audio Note DAC digital board, issue 01 PCB-290/01. There's two 100uf caps meeting supply from the separate PS board (C3 & C6, meeting the center-tapped PS), and four more after the resistors (C4, C5, C7 & C8). Can we increase capacitance ? Second, there's a 47uf cap before, and another 47uf cap (C1 & C2) right after the regulator (TR1). Can we change capacitance ? I was thinking maybe as much as 4700uf before and maybe a BG-N afterwards. I am horribly ignorant about digital circuits and I am afraid changing cap filter values could affect behaviour of the chips. P.S. I've already BG'ed the analogue board. Thanks in advance for any comment
