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

To the OP

Because cable audio performance and its overall system synergy (... or lack of it ...) is a well-travelled and oft-repeated theme that is always intuitively determined by the following two main factors in lock-step:
(a) cable selection and performance optimization is entirely your bespoke unique audio system dependent; 
(b) the unique warts in your bespoke listening environment (... as big a influencing factor as (a) above ...) 

Hence, it is impossible for outsiders to make any further comment over and above what has already  been offered up. 
You already have have numerous recent posts below on the same general theme. It’s now entirely up to you alone to experiment further in your system, especially as you appear to have already distilled your options down to your own personal faves.

Dear akg_ca,
My sincere thanks for your unhelpful input. Since my system has changed over the years and my inability to demo cables due to where I live, I seek opinions on what is available and in my price range. I would rather field opinions from real users instead of the mass media reviews. Feel  free to refrain from reading or posting any of your answers or opinions to my questions.I'm merely seeking others opinions. If you feel put out or offended by my numerous posts, feel free to skim over them and move on.
cheers and happy listening,
shawn
As someone who shotgun bi-wires I’d recommend putting those $s into upgrading other components first unless you think they’re all up to where you want them to be.  I also agree with others that if you haven’t replaced the stock jumper plates with good-quality wire jumpers I’d consider doing that at a far lower cost before employing many feet of expensive speaker cable.  What I’m saying is, there are many other ways to spend money on a system that yield more improvement per dollar than doubling your speaker cable, at least in my experience.  For what it’s worth.  
This is a tough one to debate. I have gone back and forth so many times, currently on a Canari 4S11 biwire config.

Previously I had a Mapleshade Helix single wire setup where I untwisted a few more inches of wire, scraped off the insulation and fed it up through the second terminal set to create my integrated jumper. Ridiculous how some jumpers cost as much as wire sets.

But after A-B testing, the Canari was noticeably better in bass and mids. I did chop off the Blue Jeans spades off the Canari and I believe that helped too.

I have a Mogami wire coming where I am going to DIY a set of biwire with unterminated connections.

So to biwire or not is a good excuse to try out different configs, if nothing else and it is fun.
I biwire....tried with and without....biwire sounds better to me.  Why not try it yourself
