I have a 5.1 setup with Ascend speakers, but I really don't want to run wires under the floor/through the walls in a 1780 colonial, so I am considering a soundbar instead for the living room. (I'll install the Ascend speakers in the great room/home theatre room). So, how does a soundbar sound compared to a dedicated 5.1 speaker set? I notice the Yamaha YAS-101 is mentioned a lot- is this the best one to get in this price range? What other soundbars do you recommend in the $200-300 range? Can I hook up the soundbar directly to the TV, or do I need to buy another receiver? I'd love it if I could hook it up directly and skip buying a new receiver (currently have a Denon 2310 AVR). Is a sub recommended with a soundbar?
