Seriously, i don't like the Sony brand for TV, most of them has slow response time, for myself I just bought LG 42LS80, very nice TV, by the way I live in USA, may be HK have already have something much better than what I have by now.....
Frankly speaking, Color reproduction of Sony TV is the best I think. When you compare the quality of image side by side. you will easily find the differenct. Check it with your familiar picture image and you can tell the difference.
