Like this, but with an android device driving the screen? https://www.amazon.com/Grace-Digital-Internet-Bluetooth-Qi-Wireless/dp/B08CD5WX3W/ref=asc_df_B08CD5WX3W/?tag=hyprod-20&linkCode=df0&hvadid=475811984565&hvpos=&hvnetw=g&hvrand=13766737458322505329&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9015720&hvtargid=pla-992698581782&th=1

I have a vintage 80s receiver and now I can airplay to it. It’s apparently a better signal than the headphone jack too, which is not really meant to output a signal for speakers, I guess. So I’ve heard anyway. It sounds good to me, easy to setup, and super convenient. Anyway, cheers.
>I would have to see someone do a mock up of the UI to make downloads easier.
This is why I highly recommend Symfonium, the app doesn't change or limit features when you're online or offline. You can navigate your library normally and search. It's just a way better experience overall.
>For me the current download page showing everything I've downloaded in one place is important.
Having a separate tab for downloads makes sense in PlexAmp given how it handles offline media, but it's unnecessary in an app like Symfonium where you can browse your entire library in "offline" mode with the flip of a toggle.
If you're using Android, check out Symfonium. It's leagues ahead of PlexAmp, especially in offline playback support. It support Plex back-ends too, so there's no additional configuration you'll need to do on your end.
If you don't care about keeping your library synced with your phone, and having to manually copy your library over – Musicolet was my go to music player before I knew Plex was a thing.
Very shameless plug sorry if forbidden mods can remove.
But Symfonium https://play.google.com/store/apps/details?id=app.symfonik.music.player as an offline first app made the offline experience completely seamless, connected or not you can browse everything in the same way, with optionally hide non offline cached media when not connected. (Properly handling artists / genre / albums with only a few songs cached)
Not a lot of people seem to be aware of this. But you can connect a Sonos account to your Plex account (https://plex.tv/users/other-services). Which means all the Sonos players in your network will be visible as selectable players in Plexamp (a bit like Spotify Connect works or Airplay). In theory you would not have to use the Sonos app for selecting music anymore and you can just stick with Plexamp. It's also nice for owners of older Sonos players which don't have Airplay.
Oh i fully understand the bar of entry for roon. That said, if you have the inclination. You could try d/l'ing the roon core software and seeing if that works. I believe you dont need to pay to use the core software (Note: I am doing a websearch currently to see if this is true). The sub, it seems, gives you access to the metadata that they curate.
The thing with jellyfin, its designed to be a media server. Media meaning mainly video, with audio as more of an addon. So relying on that to just serve audio may not be that good.
Navidrome seems to be the free solution you are looking for. However, it is more work on your end to set up.
As for plex/plexamp, I have had no issues casting 24/96 to my receiver via chromecast or line-in/headphone jack from laptop.
I would guess that your onkyo natively accepts 24/96 & 16/44 when it is accessed via its own app. It has all the hardware to do so, but only accessable via onkyo remote3. hmmm.
Ok. You have till nov 29th to purchase plexpass for 25% off. I'm sure if you sub to the /r/plex you can get notification on the next discount which I think will be around christmas. Install plex, and get the free trial. See if it works. If it does everything you want it to do. Bang, get the lifetime pass. If not. Cancel the sub and we work on a different solution. I still feel that Roon (barring price) is the best solution. I will cavate one thing about roon. I am not a roon user. Once I move, and build a new NAS+ server computer. I might use roon to do my local music streaming and use plexamp for mobile. I don't know. It will depend a bit on the listening habits of my SO. If my SO loves the sonically similar mixes a lot, I might forgo getting roon. I can justify roon's upfront cost for like 10+ years of service.
