Agree, in my 250W Class D I have two 47,000uf Mundorf M-Lytic caps. These caps are massive and ultra low ESR. I went to discharge one with a 100ohm resistor and could draw a blue blame a 1cm long off the cap for about three seconds.

my 1981 Threshold Stasis 3 amp with 100 watts/channel had. It used 50,000 uF @ 65V rails for 105 joules.
Caps are cheap. Use them liberally for improved resolution and dynamic punch. I learned that lesson long ago from Frank VanAlstine's Dyna modifications.
Back in '76, I boosted an Audire One's power supply from 20,000 uF to 80,000 uF and installed a new bridge. The difference was significant . :)
Not sure if you have read the article which claims your diodes or rec bridge has to deliver 100A short pulses to keep the first cap charged. And that the wiring from bridge to first cap is generally never heavy enough. In this build I soldered the rec bridge direct to the first cap to ensure no loss even through heavy wiring. I also doubled wiring from tranni to bridge.
But I hear and understand what you are saying. And agree.

is not what I've read - it's what I've heard.
Weak power supplies, regardless of the wiring used don't cut it.
