I could see a noticeable difference between my sony 7700/xbr200 and my friend's sony 9000/xbr400. The images seemed more solid and three dimensional. Not enough for me to upgrade though. The 7700 has a HUGE advantage over the 9000 in that it plays all of the vcd (video cd) formats.
My computer w/ Sony gdm-fw900 24" flat crt beats both of these.
