I'm looking over a few different receivers that either have MutliEQ or MultEQ XT. I'm not entirely sure, but I thought I read that the higher version, XT, will only help if you have satellite speakers. I'm only going to be running a 2.1 system at the moment (pair of RTi4's and a BIC F12) but will eventually get a center channel. Is the higher cost for MultiEQ XT worth it if only running a 2.1 or 3.1? Or does it only show during a 5.1 or 7.1 setup? Any thoughts would be much appreciated! Thanks!
