I think it's just that some people are making it sound like the HD650 can sound as good as an HD800 or a T1 if you feed it with amazing equipment... it's gonna sound good, but it cannot beat technical superiority. The bottom line is, the HD650 improves more than other headphones if you spend more money on equipment. But it's never going to beat any of the headphones that are 3-10x the price, it just won't.
Everyone take a deep breath, put on your cans and enjoy your (compared to the majority of the audio out of there) top of the line sound...
.... As if you didn't have them on already
