Alternatively you could buy something like the Yamaha MusicCast WXAD-10. It’s a little Spotify Connect enabled box that you plug your speakers into and it has a price tag of about 140 EUR in Europe ($160).
I haven’t tested it or listened to it myself but the first and only review I checked was favorable.
That’s not to say that one should buy an AV receiver for this purpose alone. I only mentioned it because (a) some people might have a Spotify Connect capable receiver already without being aware of it or (b) they are planning on buying a receiver anyway and so might wish to consider this alongside their other criteria.
It does... also got a google home mini that I use with it (was bundled in with something else I was buying). The voice recognition seems to be a bit better with Alexa though.
