I have a standard PSU PCB from the DIY Audio store. 8 x 15000uF caps with the regular 8 x 0.47 ohm resistors for an F4 amp. I now got these sweet 60 000uF mepco - electra caps and would like to add them to the supply if it will make an improvement?
Where do I place them in front or behind the standard PSU?
Do I make a CRCRC or CCRC or CRCC, which would be best?
Any suggestions?

I went with the "standard" Pass CRC power supply, but then added another RC stage for each amp channel. See the pics, at:

Works fine. Ripple on the 'scope is extremely low, even at high current levels. (Sorry, I don't have the actual measurement data handy at this time!)

The drawback of adding an ekstra R, is the loss of dynamics. So if the ripple is not too high to live with, it might be better to drop it.
Not if you follow Andrew's words as I understand them and the sum of both Rs remains the same.
Otherwise both voltage drop and current drop would increase. Just make the last C bigger.
Yes Ticktock, you read correctly.for the same voltage drop
and Audiosan di not read this
CRCC will probably result in the most current capability
If you have the space and a supply of cheap inductors, try CRCLC...!
That is a very good idea. Thanks!
