I've been considering building a Zen (revisited) amp recently, and an idea just hit me. In 'http://capacitors.com/pickcap/pickcap.htm', it says that, in general, higher voltage electrolytic capacitors have less distortion than lower voltage electrolytic capacitors. Considering this, what would be the effect of replacing the two 2200uF/35V output capacitors with eight 560uF/400V output capacitors? Has anybody tried this?
In addition to lowering the created distortion, I think this change would also increase the output current capabilities, as it should lower the ESR and ESL, and raise the safe ripple currents. Unfortunately, it would increase the amount of PCB space used, and it would increase cost.
Thanks
