I`ve got a yamaha 440 which comes with ex and es and i`m wondering if it was worth the extra money. As on some dvd`s that support 6.1 there isn`t really that much to write home about over standard 5.1 . Now i come to think about it .Are modern living rooms suited for 6.1 as i have only got about three feet behind me for center rear and the left and right rears to the side ,and feel that the center rear info gets a bit mix up with the other surrounds to be notice. the depth between speaker might not be enough like in a proper cinema. does anyone have any views on the subject.
