You get what you pay for, too. The B&W setup is about $1700 with the amp (I only had to pay $250 for the amp), but the soundbar was about $170. It seems difficult to spend that kind of money when something 10x less will do, especially without hearing it in your living room first. But after hearing it I'd absolutely spend the whole $1700 to get this system. I do get 10x the enjoyment out of it, when it counts.

Next I'm probably going to surprise my wife and install some bass-shakers inside my couch for the full movie theater experience.

IME, a soundbar sounds terribly flat and lifeless compared to some good (B&W in my case) speakers, even at moderate volume. I switched from a 500€ Marantz amp to an 80€ SMSL SA-50 btw, these things sound amazing and I recommend class D amps to everyone.
