PSU for 5 Channel Gainclone: wich configuration should i use?

[Bassterror]

Hi

I've got another question considering the 5 Channel 3886 Project for my computer.

I think about how to build the PSU. Ive got two 330VA/2X20V Toroids.

I think this is nonsense in practise but anyway:
What is more important, separation between left and right or between front and rear?

So

-one rectifier for FR, RR
-one for FL, RL
-and one for the center

Or

-one for FR, FL
-one for RR, RL
-either another one for the center or put the center to the front or rear group...

Each rectifier gets 10mF + snubber like in the 3886 manual at Cipamp.com.

2+3 or 3+2 is good a configuration,ie FL,FR+C,RL,RR or FL,C,FR+RL,RR.
