Hi All
I have several interrelated questions about WiiM Pro features that I hope you can answer, so I've combined them into a single post.
For context, I use Apple Music on an Apple TV 4K connected to a Sony Bravia TV. The TV's Optical Out is connected to the WiiM Pro's Optical In. I have an Arcam A90 amplifier with Monitor Audio Silver RS6 speakers. I've connected the WiiM Pro Line Out directly to the A90 and the Optical Out via a Topping E30 DAC for comparison purposes. The room is 4m x 6m, the speakers are positioned near one of the narrow walls, and I sit about 2.5m from the speakers.
I became interested in the WiiM Pro after helping a friend experiment with the room correction feature on the WiiM Pro he bought on my recommendation. The results with his room and equipment were quite profound, so I ordered one in the hope I might experience a similar improvement. However, the results with my equipment and room are far less dramatic.
So, to my questions:
1. Here are before and after pictures of the EQ curves generated by the room correction feature on the WiiM home app:

Should I be satisfied with this, keep trying the procedure or manually adjust the resultant EQ? Or am I lucky there isn't much opportunity for further correction via EQ?
2. Would you expect to notice a difference between the DAC in the WiiM Pro and the Topping E30?
3. Although I know the TV is sending 24-bit 48kHz digital data, the now playing display on the WiiM Home app says just LPCM, unlike when I stream from Wi-Fi or AirPlay to it:

Why is that? My Topping E30 shows 48kHz when I connect the TV directly. Is this just because the app doesn't display the LPCM input characteristics by design or oversight, or am I missing something?
4. When I switch the Audio Output between Line Output and Optical Output, the WiiM Pro annoyingly switches the Audio Input to WiFi. This seems like a bug to me. What do you think?
