Hey everyone. I just purchased a new Axiom setup to replace my Bose cubes (hindsight is 20/20). I purchased M50ti's for my fronts, Qs4s for my surrounds and a VP150 for my center. I have a Sony WM40 sub and currently have a Sony STR-DE545 receiver. I am looking to upgrade my receiver sometime this fall but really have no idea what to look for. I am thinking of something in the 500-600 dollar range. Any suggestions as to what would maximize my new set up?
