Sony HT-A9 with Bass Module vs Samsung HW-Q990B

The Samsung HW-Q990B and the Sony HT-A9 with Bass Module are two very different setups. They're both very versatile Dolby Atmos soundbars, and the Sony soundbar's unique speaker design means that you can place them anywhere in your setup, resulting in a better soundstage. That said, the Samsung soundbar reproduces more low-bass. It gets louder, and there's less compression at max volume, too. With its discrete center channel, the Samsung soundbar's vocal reproduction is better, too. Both bars will please most listeners, but your personal preferences will decide which is best for you.
