ProtoDAC TDA1387 X8 project

The two electrolytic capacitors C3 and C4 are in parallel, and the total capacitance is C3 + C4. Yes, any combination of 1+ caps for 2000uF total, but 2000uF total is just what I think sounds good in the circuit. Others might like more or less total capacitance, and different capacitors. There is a limit in terms of the available space, but I would encourage some experimentation with C3/C4, as the sound can change considerably.
