saw the Sony RHT-G800 in a shop and it looked great and I liked the idea of not having to clutter the living room with extra wires and speakers. However, I am not sure whether the extra money is really worth it, as I don't mind having the extra speakers in the living room if it makes much difference. I have seen some offers of DAVDZ630 to go with the Sony TV I am thinking of buying, but I am a little bit of a newbie when it comes to all this. Which of these would make more sense to me? I don't understand the difference in the sound (from the tech specs) either, is one superior to the other? Or is there something else I should consider buying for this kind of money? Many thanks in advance.
