with 4 pair 5pair 6pair same power, for five or six pairs stress for drivers.

That gives advantages if you use six pairs.
1.-power increases.
2.-votaje to the PLS is the same.
3. - We need to increase the font ampreraje.
4.-As to amending bias amperage.
5.-If aumeto the eight or more pairs to get some advantage.

Postscript: Veljko, thank you very much for uploading all this information.
