Works from Apple and Google mobile devices with Spotify
Both of these solutions allow you to use any speaker/amp setup you choose. And if you truly care about sound quality, this is the only path.
How do else could one Airplay to a ‘dumb’ stereo without something to act as an airplay receiver?
This is using an iPhone 16 Pro to AirPlay to a stereo pair of Sonos Five’s that are connected using Ethernet.
AirPlay isn’t a great choice if you are concerned about audio quality anyways - if you’re using AirPlay 2 you’re using 256kbps AAC, so it should sound the same as Bluetooth (or worse if you are comparing something like LDAC).

Sonos never wanted to work with Apple, so I can understand why they'd never make it work.
