I am probably known for making a gozzilion pcb variations of the P3A the latest 10 years.
from all the one that worked the best was the one that had the electrilytics very next to the output transistors.
That pcb was a nightmare to install heatsink but yes it worked the best.
So that brings in mind designs in pictures of a member federman if i remember well that had similar style with one electrolytic per one mosfet on his pcb... Ok mosfets have other demands but the idea is close.
So here is the idea in an amp that cost and size doesn't matter...
250 w power 12 outputs per ch
Imagine arrangement like M03 Style where distribution of outputs on the heatsink is one P and one N and then one 10.000 uf above and very close on each transistor.
Dual mono and after supplied each rail will be connected on the pcb to be unified
Then after that a weird thing jumped into my mind
Is there any point on having one dedicated rectifier per set of capacitors? Will this add anything to the all system?
It means that each ch will have 12 capacitors and six rectifiers....

Interleaved placement of P and N devices is a good idea for sure.
Also having bulk capacitance on the OPS PCB.
10.000uF may be difficult to get close, but since you are going to have many caps para in the end, less capacitance per cap will do fine.
Place the star pont on the OPS PCB for smallest loop area.
Extra rectifiers are pointless.
