Re: You guys.
Yep. SONOS systems are Linux boxes. You can even download the source code (not to their fancy proprietary bits of course, but to the bog-standard GPL components).
I'm with Chris on this one. I *LOVE* the SONOS systems. I have a bunch of them in my house (3 play-5's, 2 play-1's in the kitchen and 4 connects to drive the surround-sound systems in various rooms).
I do have some really fancy audiophile speakers (JM Labs Focal Beryllium speakers) but the systems I find myself listening to the most are the stereo paired SONOS Play-1's in the kitchen, and the stereo paired Play-5's in the master bedroom, linked with a SONOS sub.
The sound really is amazing. Regular non-audiophile people listen to the bedroom system and just go "Oooh, that sounds different. How does it do that ?" It's the depth and richness of the sound that the SONOS sub adds I think. I now listen to music all the time at home as it's just so easy and convenient (controlled by my Android phone).
Oh yeah, one other thing. Wired is the way to go. Wireless just *SUCKS*. Always :-). All my SONOS boxes are wired (the house came with gigabit already plumbed into every room so that was easier :-). Even the one too far away from the wall-plate is wired via a ethernet-over-power box. Wireless *SUCKS* :-).
Only problem is convincing the wife to let me add more zones :-).
