I'm at a tipping point - I absolutely love Sonos - first and foremost because of it's ease of use - listening to your favorite music in less than a minute out of the box, the ease of searching and playing content in the app is so simple anyone can do it... second because of the flexibility to control room by room differences or just grouping... and third because the sound quality is pretty good. But it feels like we're at a tipping point between the next gen of ease of use, voice. I have an Echo in my kitchen and my kids have all but completely abandoned Sonos simply because they can tell Alexa what to play in a couple seconds. I want to add a playbar and sub to my system. I've seen Sonos CEO comments about doubling down in voice and experience. But I'm struggling to drop $1400 without voice control... I'm sure whatever voice control Sonos builds, with Amazon or other, will be superb, but it would be a whole lot easier to keep on the Sonos train if I knew I could use it with my current Sonos products (meaning I could upgrade my existing speakers at whatever future point it was available) and that voice would not obsolete everything I have and I'd be out $1400 for the latest purchases not to mention the Play 5, 3, 1's, connect. Any view on whether the Sonos voice solution would work with existing speakers - because of an add on mic or software update or ????
