I've been wondering for a while what the alternatives are.

I've got a Denon amp which has Heos, had random Alexa/Google Home devices previously, random amps with just Bluetooth or line in whatever. Thought there must be a way to sync these things, think previously there was the Google Chrome audio?

The WiiM devices seem nice but is that the price of entry to sync various unrelated audio ecosystems then?

Edit: had only seen the price of the highest end ultra device, this is actually very reasonable..
