I purchased M50's about 6 months ago. Here at home the consensus is that it is the best family purchase in years. They are hooked up to a Yamaha RXV765, 47"Vizio LCD, xbox 360, and as of two weeks ago a Samsung BD C6500 Bluray player. We are always pleasantly surprized at how much we now enjoy music in the house. TV dialog is so much clearer, especially at low volume levels. Due to the room layout/acoustics I don't believe I would experience significant improvement with a center channel. If you want to simply enjoy listening to your music I can highly recommend the M50's. If your looking to set up a dedicated HT I would add in this order, sub(s), surrounds,and then center.
Good Luck!
