Great summary this, and like you
@Brooko I never experienced any of these issues while owning the M9. In fact I found it to be a very capable player IF it matches your use profile. I also keep my albums quite limited and selected, and generally use folder view (although with the M11 I'm finding myself using album view more often simply because it's so fast and intuitive). The issues I personally had with the M9 is speed - or lack thereof - compared to most modern devices, but that's not necessarily a flaw because with a little reading you'd know it's not meant to be a speed demon. I would say FiiO tried to cram too many features in to it and didn't back them up with adequate hardware, so users buying it to use those features (like WiFi streaming) will understandably end up very disappointed when they discover they can't stream Tidal to their LDAC BT headphones at the same time. What killed it for me was the piss-poor WiFi range and limited WiFi support (again, it's in the specs, but still...), and the fact that I couldn't get Plex to run because of the whitelisting. I had no issues with the sound or general performance, and music playback was stellar, but if you need a bit more flexibility, there are MUCH better daps around for not much more money (M11 anyone?).
