Streaming/casting Amazon music to Sonos connect or an Iphone as endpoint

Hi All,

I've been using Spotify for many years now, tried Tidal and didn't like it, now I would like to check Amazon music service.
I have a Sonos connect and cambridge audio streamagic serving me as streamers( the Cambridge cannot play Amazon music).
The Amazon music app is installed on my Iphone and configured on my Sonos, when I'm using the Sonos S1 app everything is working and I can control Amazon music playing on my Sonos but I don't like the "interface" of the Sonos S1 app which is a bit limited and dated compared to the Amazon music app.

Is there an option that I can control the music playing on the Sonos from another device using the Amazon music app like with Spotify using Spotify connect feature?

Does anyone knows what is the audio quality that I'm getting when I'm using Amazon music playing on my Sonos (the file/song audio quality is not showing on the sonos app like in the Amazon app)?

Thanks
