Had me a LG bought NB3530A 2.1 Soundbar and as the LB671 was on offer a few days later, I ordered this. Now I have compared the sound via built-in sound system and on the soundbar. If you set the sound system to the TV good, the sound is really great. A tick better, of course, the Soundbar - but for ordinary users, an unnecessary cost factor. If you read the recessions, how to install the TV is not a problem. For me the first time and went ratzfatz. Subtleties of settings you can do so gradually. Picture and sound are really great! Switching ... well - you can get used to it. The Magic Remote is funny and everything goes faster. 3D I have not tried yet. Only because of the switching time and the Program Order (before it now creeps me something) I give four stars. For the price but highly recommended !!!
