Note that this model is the S95C series. There's an S90C of the same size which costs 40,000 less and has slightly lower brightness and doesn't have the connection box. The connection box is one of the greatest features of this S95C. It eliminates the clutter of twenty different cables hanging off the TV.
The image quality is outstanding. I knew that OLED TVs were great, but I now know that there are quality differences among even OLED TVs, and this one's colour brightness, contrast, lack of spillage of lights from the brightest white subtitles being shown on inky black backgrounds, are all outstanding.
The build is amazingly thin. It fits flatter against the wall compared to most other TVs. One of the reasons it can do this is because all its connections are drawn away from the main panel to the connection box which sits in my audio rack.
The sound quality is nothing to write home about. I guess all modern super-slim TVs are disappointing in this area. Anyway, the sound quality of TVs has never mattered to me -- I've always found TVs to have horrible sound. This TV's sound is no better than my 12-year-old Sony, maybe even a shade worse. I always play all TV sound through my audio system, so it's never mattered.
One side effect of getting this large TV with outstanding brightness, clarity and contrast, is that I can no more watch my old DVD videos. The minimum resolution I need now is Bluray or full HD. DVD videos look too grainy. This is the flip side of quality step jump I guess.
