Samsung HW-Q990H vs HW-Q990H with Music Studio 7

The Samsung HW-Q990H with Music Studio 7 is an expanded version of the Samsung HW-Q990H. That said, the expanded setup will represent a step back in performance and features for most people, severely limiting its use cases. The expanded setup can only connect via Wireless Dolby Atmos with a Q-Symphony-compatible Samsung TV, which renders the standalone bar's HDMI passthrough capabilities and DTS support obsolete, while introducing intra-channel latency and disabling the graphic EQ. With stereo content, the extra speakers essentially function as duplicate stereo channels, which can muddle the stereo soundstage's tracking, resulting in a more bass-heavy and less balanced sound. That said, while you don't gain any extra stereo or surround channels, the Music Studio 7 speakers do give you two extra up-firing drivers, which boost the verticality of Atmos height content. All in all, factoring in the cost and ecosystem exclusivity of the expanded setup, most people will want to stick with the standalone bar.
