Very similar line-up to the original Sonos boxes, except they released a lot more speakerless hardware. Open source server (that could be run from the Touch model) which is still maintained and improved. Streaming options. House-wide sync. All for half the price of the Sonos.
It's especially galling reading that list of Sonos complaints. We've got regain support, good .cue handling, 24/192 and higher playback depending on your hardware, you could even do bidirectional Airplay and bluetooth (with some kicking and screaming)... And oh yeah, you could make your own players because it's all open source, open spec.
And a feature (for me), none of this smart rubbish.
For those of us that have a household full of it (and spares) it's still an amazing system... but Logitech ultimately binned it. I guess only selling one pile of kit every 15 years didn't seem good enough business for them.
Le sigh.
