New Sonos Operating System

Sonos will introduce a new app and operating system, called S2, in June. Among other things, S2 will provide support for HD music files. I thought this article did a good job explaining the different options if you have a combination of S1 and S2 components:

LowFi player does HD files.  Not impressed until they update their players
Thanks for the info I use my Sonos for TV and my wife uses for music
