I have have this system for a year , and just can not convince myself I be happy with it . it seem to have different volume range with dvd , cd , and feed from hdtv . so while it will rattle the window play a dvd , I can hardly get the gain loud enough to hear quiet dialog on some tv program . the CD reproduction be tinny and not acceptable for music listening . as far as surround sound ... none that I can tell . do not compare with the 5.1 that I cobble together with a amp and some old speaker . so if you just want to play you dvd loud in a small room , this unit look good and provide a great picture . but if you be look for a home theater system , dream on .
