I don’t do Chromecast but I see they have a Pandora app. That makes the Primare NP5 perfect for you. It also has its own phone app/player, Spotify Connect and claims most other services for when you graduate to Qobuz and/or Roon etc.
All you need is an external DAC. You can start with $10 to $100 but I recommend a used (eBay or Schiit refurb) Modi Multi for <$200.
Total outlay $800.
If I was visiting England (like I had scheduled this year) I'd pick up an NP5 for myself @ <$500.
Crutchfield will help you get it going.
Good luck
