What do you want to use the 2 extra QS8s for .. music in the other room (Zone II setup) or as a 7.1. If its the latter, the QS8s will be an awesome choice. For a Zone II setup, probably you should try the bookshelves. The only thing I dont like about Zone II setups (esp HK receivers - dont know what you've got), is that they dont have separate bass/treble controls
