Ripple voltage - safe zone

Patrick, is the amount of ripple Voltage a good indication for the need to increase Capacitance? Say I am between 5-10% ripple Voltage (sort of ok zone, right?), would adding more Capacitance still lower the ripple and be beneficial?

Can one add too much Capacitance? More specifically: is there a maximum amount of Capacitance you would advice for a Mamba Monster or XL2?

Thanks!

You can't add too much capacitance... More is always better, but diminishing returns above about 1.2mf (1200uF)

Percentage isn't a good indicator either, the absolute ripple voltage is the best value to use. I prefer to see a ripple voltage below about 2V in my setups.

Thanks!
