I'm fed up of trying to make a echo dot permanently muted work as a Spotify streaming device for my powered speakers. The account management for a multi user household and linking specific Amazon accounts is broken. I want a device that allows basically any user on my home wifi nw to pick a device to stream to like a Chromecast.

I've been still shocked about the cost of a raspberry pi these days, but is 100 dollars for a bundle of components really the best option out there for a straight forward streaming receiver to connect to some powered book shelf speakers? Are there any other options under 100 bucks?
