After numerous speaker wire experimenting I've come to the conclusion that running my bi wired Ref 3A Grand Veenas with a one metre single run of Cardas Golden Hex 5C and using the Ref 3A solid core jumpers is the best solution so far.
I should add that I run the speaker wires in the diagonal wiring scheme, which also sounds better than any of the other options using jumpers.
