After years and years I finally pulled the trigger and bought a soundbar! I went with the Klipsch Flexus Core 300 . Besides the stupid name, it has already made quite the difference in my living room – even without the optional subwoofer and satellite speakers. I am quite happy with it, even though it was a bit expensive. I still have to resolve a couple of HDMI CEC issues, but I am sure I will find a solution soon.
