Big telly!
Be interested to hear what you think of your LG soundbar set up, I know my brother's Sonos kit sounds pretty good. That Dolby Atmos thing does make a big difference. Is it wireless?
Only thing that might be a sticking point for me is that you may not be able to use an existing sub with these soundbar kits (though admittedly I haven't investigated this). I already have a decent REL sub, be a shame not to use it.
