"What a great product!"4.5 starson by Rogerinnva
Pros: Excellent sound, SUPERB file manager, nothing else is even close!
Cons: Lack of headphone jack (but that's pretty trivial compared to the high points)
Summary: Sonos has a winner here. This should do for high-fidelity home listening what the iPod did for low-fidelity on-the-go listening. My Sonos setup has allowed me to put thirty years of audiophile pleasure on my wireless network. Quality, fidelity, simplicity -- oh, and it manages metadata tags better than iTunes, MusicMatch, or any other player I've come across.
I do wish it had a headphone jack on the music controller, though, and a more full-featured equalizer / sound processor and analyzer would be nice. These aren't real criticisms, though, just a user's comments on some nice-to-have features that I've wished were available.
Congratulations to the Sonos team!
