There is also a chance that some people expect miracles happening once they connect their new Home Theater. I would strongly suggest in that case, apart from calibrating the system and making sure everything is connected right, they go to some higher end HT store to listen, to compare. An HT cannot be a miracle, can only be a system comparable to some of the best setups in a high end store.
