Biwire NBS with....

I have recently sold off my Kimber Bi-Focal (Bi-wired of Monocle) and bought a single run pair of NBS Master3 (given my budget constraints). The Master3 has enhance the low octave quite a fair bit. However, the highs seem a little reticent.
Is there a cheaper solution (if any) to buying another pair of NBS cable in order to biwire my speakers?
Someone has also suggested a pair of NBS jumpers - I am skeptical if the effect is great.
Has anyone has been successful in matching a pair of NBS speaker cable with another cable say like an Audience AU24 or even Belden 8461(?)?
Appreciate your inputs.
