From the input of the Klipsch faithful, I have chosen this as my planned upgrade path: I currently use RB5's for front mains, RC3 center, RSW-12 sub and Blose acoustimas for rear surrounds, driven by an H/K 520. When the new ref's come out, I plan to upgrade the front mains to RB75's and move the RB5's to the rear surrounds (Blose going to the den!). I'll also move the RC3 to rear center, replacing it with an RC7 in the front. I'll have to add an amp to drive the rear center or just wait for my electronics upgrade. Next year I want to upgrade the H/K to Rotel separates and maybe jump into the DVD-A/SACD fray. I think this will eventually be a very good system...
