Our Verdict
Samsung HW-Q930C
Samsung HW-Q990D
The Samsung HW-Q990D has the edge over the Samsung HW-Q930C. The Q990D is an 11.1.4 setup, and it supports HDMI 2.1, so you can passthrough a 4k signal at 120Hz, which is well-suited for gaming. It can also get louder with fewer compression artifacts. The 9.1.4 Q930C is nothing to scoff at, though. It offers a similarly balanced sound, supports height content, and even has a similarly excellent build to its higher-end cousin, but it's available for less than the Q990D.
