I have been out of surround sound for a while I had some Dibeisi speakers they were ok but the center was too small as I had 3 home made 3 way speakers on each front with a power amp pushing them. I blew a few of them up and bought the m80's. I watch a lot of movies and wanted to get at least 5 speakers hooked up. I am pretty happy with this setup for now. I don't know if I will even hook up the center surrounds I found they didn't really do much in most movies. Im going to buy an ada 1500 2 or 3 channel amp or try and find a used bryston 4b, my amp actually does fine for movies but when I listen to music it is struggling at only 110 watts a channel.
