cannot believe this thread has went on for so long yet nobody has mentioned yamaha.
yamaha are the number 1 manufacturer of decent soundbars, yes other manufacturers make decent ones but yamaha are at the top of the game.
much like when someone mentions headphones - sennheiser, akg, beyerdynamic, etc are the makes you want to look at as they specialise in this sort of thing.
sony are a jack of all trades master of consoles and nothing else. i would only use a sony soundbar if i got it free with my tv.
also i don't get why some people must have matching gear, i use a yamaha soundbar with a panasonic plasma, with a sony ps4 and a Virgin Tivo box.
Take a look at the yamaha range and buy whatever suits your budget, yamaha soundbars start at £100 but go all the way into the thousands. their audiophile quality soundbars start at £500+, you get what you pay for in the end.
