High-resolution format support is generally viewed as useful and broad, though one reviewer heard no practical difference between very high sample-rate files.
Pros: AirPlay compatibility, Chromecast compatibility
Cons: Spotify Connect reliability, Status indicators
The only opinionated format evidence says the simple stereo format should sound natural with most content rather than chase surround formats.
Pros: Setup simplicity, Bluetooth connection stability
Cons: optical, Smart features
Audio format support was broad, but reviewers noted that higher native resolution playback depends on wired connections.
Pros: Soundstage height, Amplifier power requirements
Cons: On-device controls, Surround sound simulation
Audio format support was acceptable but not unlimited, with 24/96 described as a reasonable ceiling for most listeners.
Pros: HDMI ARC, Stereo imaging accuracy
Cons: Surround sound simulation, Bluetooth codec support
Reviewers treated the Hi-Res positioning as mostly marketing, not a meaningful audio-format advantage for a passive speaker.
Pros: Value for money, Home theater integration
Cons: Audio format support, Loudness / maximum volume
