Our Verdict

Samsung HW-Q900A

Sony HT-A9

The Samsung HW-Q900A is better than the Sony HT-A9. The Samsung is a 7.1.4 setup with a dedicated subwoofer included. It can reproduce a more extended low-bass, and it gets louder. It also has a better center performance as well as more sound enhancement features like a graphic EQ. That said, the 4.0.4 Sony is still a very immersive setup. It has discrete satellites, and its soundstage, surround, and Atmos performances are better.
