Hello all. I just moved into my new home and I'm looking to put in a multi room sound system to listen to music. What I'd like to find, and I don't know if it exists, is a system that has some sort of base station that I would sync my phone to and then there would be "satellite" speakers that sync to the station wirelessly (bluetooth or wifi I don't care). I don't want to do like an Echo or Google Nest Audio. I don't want something that sits on the cloud. Does something like what I described exist?
