It seems to me most tv manufactures have decided that all we really want is super thin sets to hang on the wall, Why ? It's the typical marketing technique of not giving us what we need but what they think we should need, Apple are great at this as were Microsoft in the past, creating demand were none existed previously. The result i s we have to buy "extra" boxes", more profit for them, if we want decent sound. To be fair CRT sets were a damn sight dearer than their flat screens and had pretty crap sound in the main, maybe a better bass end. Lets face no TV has ever been produced that gave good stereo,it would have to be least 8 foot wide !
Considering a 42 " LG can be bought for about £ 300 another £150 spent updating the sound, a 2.1 or a bar system is not out of the question. Personally I prefer this option, I pay for my Telly and then choose the sound system that I require.
