If it was me, I would want to see a very thorough review of the room correction first. With the X4800H you are getting tried & true solutions in the form of Audyssey and Dirac. With the Sony, who knows what you're getting? Some soundbar tech?
Fair point. I am intrigued by the 360 reality audio tech in Sonys and what Andrew Robinson and other reviewers said about ability to pin point exact location of audio effects (especially in FPS games). Problem is my 4800h return period ends in mid March so cannot wait long enough to see in depth Sony reviews. May bite the bullet and get the Sony to try for a few weeks and decide between the two
