fred, I truly feel a good 5.1 setup can rival a good 7.1 in most cases. You also have to remember that most movies are encoded with just 5.1 (even most Blurays) 7.1 is great if you have a big room, but for a bedroom system than 5.1 will be more than enough. In fact with my set-up. I barely hear the rear back channels, but then again I mostly watch HD Sat TV in 5.1, I try the simulated 7.1 but it doesnt really add much. I have it but barely use it, only on that rare occassion when I watch a Bluray or HD-DVD in the bedroom setup, but most movies I prefer to watch on the main system (which does benefit very well with 7.1)
