Default Introducing a New Horse to the Stable

IF all you are doing is wanting to power speakers at a reasonable listening level in a reasonably sized room, and you do not want ear-bleed levels, your major task in this case is managing transients.

Your plan to use a large amount of capacitance will address that fairly nicely. And if your amp "breathes" at high volumes (you will absolutely know if that happens), then and only then consider (a) beefier power-supply(ies).

I run a pair of AR3a speakers (4-ohm, nominal) in a fairly small room (17 x 14 x 10 (feet)) with a 60 wpc/rms amp, and it does fine at any listening level I would care to use. It has about 8,000 uF/channel of capacitance.
