This might be a good case for piece building the system, start with the best sub you can afford from Axiom or any place else, SVSound, Epik, Elemental Designs, etc., then add the sourrounds and center channel and finally make the upgrade for the mains. I mention these last as you say you are happy with them and are having no problems so why replace them now if you don't have to.
