Many WiiM users are asking why they don't get 24-bit/192kHz but 16-bit/44.1kHz from their streaming service while listening on Mini. Here is list audio resolution that some popular music service offers. Since Mini outputs it in the bit perfect fashion, you'll see the same bit-depth/sample rate pair in the "Now Playing" UI on WiiM Home App.
