I am going to hijack a bit here because I have a similar question about DACs. Take a look at the inside of a Denafrips DAC, they have large arrays of capacitors, what is their purpose in this case? Follow up question, do large arrays of capacitors represent a higher risk of failure or sound degradation given the increase in odds? Not picking on Denafrips BTW, they are just popular and seem to favor this design.
