A:Answer I don't have any issues - it depends entirely by your source. I have The Samsung 8K TV 900RB, Xbox One X, Nvidia Shield Pro 2019 and a gaming DELL laptop. (the Dell laptop and the Shield are plugged in the sound bar, the Xbox to the TV for now). I had also the previous model (HW-950) and it had problems with the back speakers and it disconnected several times (had to synchronize again the back speakers and subwoofer many times as it lost connection). However, the speakers and the sound bar itself are the same as the previous model, the only things is the Adaptive Mode and the Game Pro Mode (super for Xbox) that work better with all system (including the rear speakers). Even the Spotify from a smartphone sounds better and if you wish on all speakers with this model. I think they tuned or they change something in the electronics, not a big difference, only a small difference with the new subwoofer model in the efficiency.
