Grace Digital?

Does any one know about Grace Digital Wireless Hi-fi Internet Radio Tuner (GDI-IRDT200) ?

This product has digital output and i wonder whether it can be used as a music streamer.
The product description says you can stream music from your PC or Mac.

I just got a Grace Mondo, which is a tabletop Internet radio. Very pleased with it so far.
did any test if it is bit perfect?
I have the GDI-IRDT200. When it works, it's great. The firmware works poorly and it reboots itself sporadically when another device connects to the wifi network. When I returned the unit for troubleshooting, they told me that there were no problems found. I'm an electrical engineer, so let's just say that I'm pretty confident in my wifi network skills.

I don't know what "bit perfect" means.
