Re: The problem with large capacitors

All PS capacitors 'compete' with the circuit for current. Small caps permit much larger changes in PS voltage with signal but return to static levels quickly, large caps maintain a more consistent voltage but require more time to stabilize. I find it unlikely - all else equal such as type, construction, quality, etc. - either is quicker than the other in delivering current at audio frequencies.

"While a large capacitor may appear to have better regulation and superior ripple reduction, it is very poor at delivering energy quickly."

Regulation is the ability to deliver energy quickly. The explanation also confuses 'large capacitor' and 'large capacity'. Would ten paralleled 10uF caps delivery energy slower than one 10uf cap? My sense is these power supplies are moving towards straight 'C' with inductive HF filtering (as opposed to using L as a regulator) coupled with a small first L as a pulse smoothing device.
