I agree with the sound first. I am still waiting for the HD stuff to settle down and the higher resolutions are just starting to come on the newer Projetors and Plasma etc. Audio doesn't seem to be changing much other than more discrete channels but in a small room I think it wouldn't be noticed as much.
