It's precisely that brightness that many will argue degrades the black levels, detail, etc. When ambient light is introduced. In no way should my, or anyone else's opinions be taken as absolute. Even when you measure numbers, something as subjective as colour representation and black level detail is never going to be the exact same for two pairs of eyes. It was in this "added ambient light" setting that I felt the st60 pulled ahead pretty clearly.
Additionally, I'd like to know how many people are going to have access to the light controlled environment 9/10. It's nice that some have the ability to build a home theatre room without light, but most people want these in their living rooms.
Anyway, the w900a is a fantastic set, no doubt, and has many advantages over the st60. But coming from someone who could afford both, I chose the st60 because of what I felt was a better class of black levels, colour representation, etc. This is a forum, and I always find it ridiculous that people can attack another person's opinion unless they preface it with IMO.
