Apple Homepod as Streamer and Speaker with Dolby Atmos capability

[OldTimer]

I just want to share my setup at my desk in a room.
Those are an Apple Homepod and a soundbar (cheap 2.0 no sub) connected to AirPort Express mini Toslink. I only use the iPhone at the beginning of the Homepod setup.

1. After the setup, I move the iPhone to different network because I don't need it anymore to stream music, control audio, connect to other airplay speakers, etc. Just using: "Hey Siri...". So, this becomes dedicated streamer (Apple Music and Deezer).
2. I found the sound quality is much better than using Qobuz airplay to the homepod specifically for Dolby Atmos music from Apple Music. So, Dolby Atmos is real deal.

I don't know why the sound become better after I asked: "Hey Siri, connect to soundbar at 100% volume". I adjusted the homepod volume at 50% before and the soundbar manually to equalize at the best. The homepod position at a table at the middle of the room. The soundbar is in front of me at the desk.

The cost for this setup:

• Apple Homepod $299
• Soundbar $50
• Airport Express (used) $30
