Ok. I am no computer geek but I have been playing with one this weekend.
It's a bit like apple airplay and a lot like sonos.
It has analog output and optical digital output. So you can use an SPDIF dac with it or use its analog output in less critical applications.
Basically you can link it to your wifi or wired home network and with simple server software (I am using minimserver for now) installed on a computer or NAS on your home network you play your music library to it.
You control the playing with an app on a smart device.
So if you have one computer but more than one space you want to play puter tunes it's a solution, up to ten units can be set up on your network. They can play independently.
It can also play music directly from your smart device, droid or apple in direct wifi mode without a network.
This is nice as my wife liked airplay but now uses a droid phone while I still use apple.
It will allow playback up to 24/96.
It even has an analogue input. So if you have a few units you could add analog radio by feeding one of them the output from a tuner you can stream from the tuner to all other wr100.
(In SA with expensive uncapped I missed analogue radio with airplay for eg so I think this is a cool feature. ). You could even distribute your turntable output I guess.
Spotify napster rhapsody are available.
It is all on the Qualcomm AllPlay platform and their site is more descriptive of the system ability. Note that wr100 does not have airplay but some Qualcomm devices incl larger NuPrime models will include it.
