What I'm hoping to achieve with this thread is answers from folks here who currently use a soundbar. I do not watch a lot of television when I do it's either a sporting event, documentary, nature show or the occasional series and movie. I think we can all agree that internal speakers of most TV's these day sound terrible. I'm just looking for somewhat better sound and clearer dialogue My first question If I get one that has the ability to decode 2.0 & 5.1 does the unit itself know to switch between the 2 specific to the programming? What is HDMI (ARC)? as opposed to Optical and I hope this doesn't open a can of worms but from experience which would you say is most preferable? Do soundbars play well with OTA programming and the accompanying audio signal?
