Hi I own this LG TV http/www.lg.com/ca_en/tvs/lg-42PT350-plasma-tv and am looking for a decent sound bar around $300. Today I bought this Samsung bar http/www.samsung.com/us/video/home-theater/HW-F450/ZA but now I feel dumb because I don't know if it works with my tv. I don't think my TV has Bluetooth. Also what is the optimal connection for your audio system? Optical or HDMI?
