Welcome sparkybird! I think most will agree with me here if I say that you will definitely gain from an upgrade to say a QS4 or QS8. I've heard the Bose systems and they do OK. However, the sound quality from an Axiom Quadpole QS type speaker will give your movies more realism. In this case it's almost day and night. Keep in mind that I'm NOT bashing your Bose speakers they are fine for the average home theater. If you go with Axiom surrounds it will match the sound quality of the M60's that you already own. I think you would be in audio nirvana with QS4's or QS8's.
