Hello SW123, IIf you connect the HW-S800D to the HDMI eARC (Enhanced Audio Return Channel) port, this is the best way to ensure high-quality audio, such as Dolby Atmos or DTS:X. It supports high-bitrate audio formats without any loss or compression.
Alternatively, when connected via Wi-Fi, you won’t need any cables, and you can still utilize Wireless Dolby Atmos and enjoy great audio. However, note that the audio will be compressed in this setup.
I recommend trying both options — first, connected via HDMI eARC and then via Wi-Fi — to see which you prefer. With both setups, you will also be able to take advantage of the Q-Symphony feature.
