it is definately the best investment, especially since my room is fairly 'compact' compared to the average home cinema.
No matter what equipment i get it will never let it perform to its best until my room is sorted out, one of the things in particular is my subwoofer, my room really is not a sub friendly room. I am sure once i get it professionally sorted it will be great.
Although it is £700 afterall, probably will be a bit more, and maybe i should do it once i get my 'complete' system, it will probably be one of the best investments i make. It all depends if we move in the near future or not.
cheers
