The blue LEDs on mine are far too bright, so when I get the time to rip open my DAC again I might do all of my mods in one go.
Black Gates are pretty hard to find and their selection is quite limited. I was also looking into Nichicon Muse and the more widespread Panasonic FS series but still can't seem to find the exact specified values. I'm new at this and was wondering if the cap's voltage rating needs to be exactly as specified. Would a higher voltage rating be overkill but work just as well (eg. replace the specified 22uF 16V by a 22uF 25 or 50V) or would it screw up the sound(or worse)?
Why would you settle for general purpose caps when audio grade caps cost only a few cents more?
