I just received the Sonos Beam and wanted to add either two Play1's or two Sonos One speakers to it to make a surround sound experience. I understand that the biggest difference is that the Sonos One can be activated with Alexa. However, if I already have a Sonos Beam that can be used with Alexa and if the speakers are connected to it, then does it matter? Is there a large difference is sound quality? Anything else I should be thinking about before making a purchase? A pack of play1's are considerably cheaper, that's why I ask. Any advice would be appreciated!
