So, firmware 5.0.613551 brought us per-source EQ. So far, so good.

Playing around in the WiiM Home app it seems that we can only ever change EQ settings for the currently active input. But how can I apply EQ to the USB input, only?
As soon as the USB input is chosen, the amp switches input to WiFi automatically. I haven't tried Ethernet so far, so I don't know how that would behave.
