What can replace chromecast audio

[matyce11]

 Hello !

I have a spotify premimum account.

I have an old hi-fi system, and i'd like to play spotify on it with my phone  in airplane mode. I have seen that I can do that with a Chromecast Audio, but it's impossible to buy it in France now. 

So, I ask you if there is anything that can replace it (not too expensive^^), and if I'll be able to listen spotify with my phone turned in airplane mode with it.

Thank you and sorry for my English, I'm Frenche 😕

You need to connect from spotify app or from speaker app.

I don't know if any speakers coming with built in spotify app.
