I have got the S300 hooked up to my Wega set,great picture and sound,but i am a little unimpressed with the centre channel. It seems to be lacking in range. All the vocals seem tinny,no rich deep sound. I am thinking of upgrading and have seen the S550. WOuld this help?? WOuld i see a difference? I only have a small room so i think the S800 would be overkill. Perhaps anoter nake other than Sony??
