Our Verdict
Samsung HW-A650
Sony HT-S400
The Samsung HW-A650 is better than the Sony HT-S400. The Samsung is a 3.1 bar, and unlike the 2.1 Sony, it has a discrete center channel to improve dialogue clarity in the mix. It also has more sound enhancement features, including a graphic EQ to customize its sound.
