I hear ya, I picked mine up the same way while working at Audio Communications. I knew I was on the way out the door and just wanted to grab the biggest and badest I could afford. So my rears are Bookshelf sized “atoms” hanging on the wall, the Center channel is twice the size I need and the fronts are “Legends” towers and both house a 10" sub mated to an atom speaker. Everything is close to 7 years old with a higher end Sony ES receiver - the only thing I would upgrade is the reciever but hate to put the money out while it’s working. I can’t swallow buying a Blue ray yet, I’ve got too many DVD’s and don’t feel like starting over with a new format!
I’ve heard good things about the Klipsch, and my father in-law just redid his system with a 60" wall mount and a really nice Yamaha 7.1, forget the name of the speakers but it is a really well worked out system.
