I’m trying to logistically figure out what products I need to get my home set up. I have in home audio in 5 zones that is not connected to any amp and am going to start the process of getting connect amps set up in some of the rooms. The only Sonos product I currently have are play 1’s from 2015. I can’t afford to get connect amps for all zones at once so would like to get a couple amps and then use my play 1’s in a 3rd zone. Can I play the same music in multiple zones with this setup without having a Sonos port?
