Im still in the Squeezeboxes with an LMS server is still by far the best music system. I have almost all the models they made and have them all over the house. With the right plugins in the server you can still use it with all the major streaming services. No need for Logitech's support as the community has long since taken it over and doing a wonderful job. And best of all they are way cheaper since you can find them used all day long on eBay in perfect condition and with more hardware options than the Sonos stuff.
If at first you don't succeed, redefine success!
