Recent purchase a Panasonic HTB688 soundbar decided to stop working after 8 months. Tragic. On its way to be repaired. Thought I'd plug the gap as it may take up to a month. So ended up buying a Sony XF9000, which boasts Dolby Atmos. My real question is this just a gimmick with a limitation of 2.1 channels? It sounds similar to the Panasonic but not a huge deal of difference. The Panasonic is not Dolby certified. Apologies for any amateurness above I'm new to the sound game. I have pressed the S vertical button
