I’m brand new to Sonos, need the most basic starting point and am totally overwhelmed reading about bridges and boosts and WiFi networks… what do I need to buy for a one bed apartment?? Looking for the most user friendly and affordable set up. Thinking the Sonos 1, definitely one for the living room and MAYBE a second one for the bedroom. Do I need other devices to get started?? What’s the difference between older models/generations vs the newest version? I was thinking of buying a used one from a friend as well. Thank you!!
