Preach! Also, do you have the Sonos One? (the Sonos version of the Echo) MUCH fuller sound and acts as Alexa for most things. Also, I like these power systems other people recommend, but I (like most people) have neighbors nearby and don't want to annoy the heck out of them. Two Play 1's are plenty for my deck roof.Nothing beats Sonos for ease of use and multi room capability, including TV sound bars, and battery powered portable speakers. They also incorporate all the streaming services really well. Their UI for the app is the best. Alexa integration is really good. For my take if you dont mind spending the money, I dont think you can do better.
A cheap version of that would be to use the Echo (Alexa) ecosystem. Offers almost the same functionality for about half the price. However, not as clean. It just feels like second place. The extra one step is annoying. But it is much cheaper and they release a bunch of new models every year.
Then there are plenty of great options where you cobble together amps with chrome devices or other streaming brokers, or even amps that have some wifi built in. For what a lot of people want to do, thats enough. For others you can get more granular with this option and more customized such as very powerful amps.
Of course there are the traditional multi room system providers. I dont know much about them, and have not really kept up with them since I looked about 10 years ago and chose Sonos instead.
