I have just bought my first surround amp. Its a sony str895d. Got it new for £175, thought that was a little bargin. My main question is this: To connect my PS3 etc to it do I just buy a TOS optical lead or do i need dome other kind of lead. I want to connet my DVD, Sky box and Xbox 360 to it. It has 4 optical and 2 digital coaxil inputs. Many thanks for your help.
