My roomate is moving out of the country at the end of the semester and is selling his Sonos Play:1 for what looks like a good price. Are there different generations of Sonos Play:1 and the latest models are somehow better than the old ones? Or are the firmwares updated on a regular basis via wireless for all Sonos Play:1? I want to make sure this is not instead a crappy deal.
What system would you recommend if I want to add stereo? This is mostly to play music from Spotify/Pandora/Playlist from my computer and then ideally sound for Sports games from TV. Should I get a second Play:1? And do I need one of those amp/Connect product? I am not sure the difference.
Lastly, is the Sonos One a better product? I don't need that Alexa stuff.
