WiiM devices support bit-perfect playback. If you want to get the best sound experience try this.
- In the WiiM Home app turn on the `Fixed output volume` by selecting Device tab -> Device settings gear icon -> Audio settings and now you can control the volume with your phone or another device you want to control volume.
- If the volume is not maximum, it will break the bit-perfect playback because it will reduce some bits in the audio signal.
