I have a PSU board with 1,000uF of capacitance after the regulator. I plan to buy a DAC board to use with it, but majority of DAC boards come with its own regulated power supply on-board.
I'll not use the on-board regulators of course, but what should I do with where the DAC board's reservoir caps (total capacitance a few hundred uF)are supposed to be?
Considering that typical impedance of electrolytics are in the order of 0.1 to 0.01 ohms the 5cm wire shouldn't add any significant impedance, am I right to say that? If that's the case, will using those few-hundred uF capacitors on the DAC board be useful or detrimental? (since the impedance of the single smaller capacitor is likely to be higher than the pair of 470uF on the PSU board)
Should I replace it with ceramic or plastic film?
