I have had this TV for about 6 weeks now and am hugely impressed with it. The sound is ok for general usage, but asnyone buying a TV like this will more than likely have a seperate digital sound set up for films etc.
The only downside is that the screen is behind a glass front which can cause reflections if there is any bright light in the room opposite the unit.
The picture is truly stunning with amazing amounts of contrast and detail. Shots of lightning in a dark sky are blindingly bright in a good way. The local LED technology is a revalation in picture technology.
I couldn't reccomend this TV highly enough.
