Just two words for you: GET IT !!!
If you want a real soundexperience, you have to buy a Dolby Digital / dts Receiver, 5 Boxes (maybe a Sub) AND an Opticalcable...
The dynamic of the Movies and Games will increase dramaticaly !
Again: GET IT !!!
N O W !!!
BTW: NO, there is no cheap solution, get the best stuff !!!
