To bi wire or not bi wire


Hello all,
I have a pair of B&W P6 speakers driven by a plinius 8100 integrated. 
The plinius has two sets of speaker outputs per channel and the B&W’s are biwireable. 
Would there be any benefit to running 4 separate cables? If so, any recommendations for cables?
The binding posts on the B&W’s make using spades difficult so banana’s would work better. 
Just asking this question because it would require a total of 24 feet of cable so it could get pricey real fast.
budget is around $500.
Thanks in advance

You will find no consensus on this question. Simply try variations of connections if motivated.  
If you already have 4 cables then yes. Maybe.  If you will be buying then no. For the same money you can always do better with one than splitting the money into 2. Duh. Or everybody would be doing it.
