Don’t confuse cap dimensions with uf value.
For example, the diffs* between the P’sound 1000 and 1000A are higher value PS filter caps w/similar external dimensions. Can’t recall Y/N for a rail voltage diff
*plus higher output & remote 12V turn-on
A 555 related note in addition to the Darlington discussion above, I recall reading “somewhere” Adcom switched output devices (ie bi-polar to MOSFETs) w/sound signature change. But don’t take my word for it. I welcome correction from the more knowledgeable.

In my time rebuilding the levinson amp so far... Most modern day capacitors are smaller than the ones used back in the day but if all of the specs are very close, ripple, esr, etc... Not that dramatically so.
The only way I have seen you could dramatically reduce the size would be compromise on some of those ratings- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
The large capacitors on the adcom 555se are hiding under the circuit boards.
