I buy this as a gift , and believe I when I say it be a terrible disappointment when I set it up and find that the sound come out of the center and surround channel -lrb- but not the front channel -rrb- be completely mangled by the receiver . I try everything , but no matter what , CDs play in pro logic and Dolby Digitial encode dvd sound awful . strangely , if I play cd or dvd in stereo , it sound great , so I believe there be something wrong with the surround channel amplifier .
