I recently purchased some Energy A2+2 mains and a EXLC2 center. I'm starting to feel like I made a mistake and should have shelled out the extra cash for the AC-300. Things sound Ok but I think that when watching TV it sounds a little better when in Stereo only. I've had the speakers for about two months. The mains were a demo and the center was brand new. Question: Do I have to wait for the center to break in a little more? I need to be told this setup is just fine to calm the little demons that are nagging me. Upgrading is my option, but I don't think it would be in the wife's field of view.
