I’m considering upgrading my speakers internal wiring

I’m looking for objective input because I’m not sure if I’m really OCD. 
I have a beautiful pair for PBN M1!5 in a Black finish which I love and sound incredible.  Peter builds high quality equipment with nothing spared. I think we spend thousands on speaker cables and transport and everything that gets to the binding posts….. And then ? Internally it’s not so great. 
I’m considering re-wiring including binding posts to all Cardas ..

What are some thoughts.
