Do I go active with my Linn 5140s ?

I currently have a partial Linn system with Unidisk SC, a 5105 and pair of 5140s. The rear setup is non Linn. I've moved to a much larger home and I'm building a dedicated home theater / high end listening room. I've reignited the old audiophile addiction and I'm wondering if it's worth spending $4k on a 6 channel Linn amp and active cards for my 5140s or if I would be better off getting a totally different setup? How much difference does going from one 5105 to an active tri-amp with a 6 channel chakra make with 5140s?
