I believe internet radio sampling rate is limited to 44.1, but...
My Jriver Id Ethernet DLNA renderer ($295) can also operate wirelessly with PCM sample rates greater than 44.1 (i.e 96,192). This is confirmed when my DAC connected via usb to the Id shows the higher sampling rates.
I do plan on replacing the Id in the future it with a device with non-switching power supply and without a fan and not limited to USB output only.
