I dont think a lot of people here have listened to many sound bars, since I fell for you I put this list together....
may get you started..
Bowers and wilkons panorama $1770
DEFINITIVE TECHNOLOGY MYTHOS XTR-SSA3 $800 or less
KEF HTF8003 $600 or so..
For surrounds, any will work, if you go def tech get there slim surrounds, kef also makes small surrounds as does bw but you can mix and match the surrounds...
Now bose, boston acoustic, energy, klipsch, yamaha, harmon, lg, samsung, also make them but if I were you I would be between the 3 I listed above...
Atlantic Technology PB 235 self powered I heard it didnt enjoy it comes with muddy bass making system though...
I would stay away from powered and more than 3 channel units...
