I currently have JBL S36s in my 5.1 setup, and a JBL S Center II. Since these tend to go for a good amount of money since being discontinued, was thinking about selling and upgrading to either an Axiom 5.1 setup or Rockets ELT setup. Two questions: Would I notice much of a difference from the JBL studios to the Axiom/Rockets? I like the JBLs, but always willing to try something new in the name of unnecessary upgraditis. And for those that have tried Rockets and Axioms, what were your impressions of each? I know they are both great speaker lines and fairly close in sound, but there must be differences. The ones I was eyeballing were the Rocket ELT bookshelf speakers and center, or the Axiom VP150, F/L Mt3i, and QS4 for surrounds. Any opinions about these speakers and their high/low points?
