USB input for Allo Boss

Can I anyhow add USB input to Allo Boss DAC? What are the solutions for the same? XMOS board or something? Sorry I am pretty new to audio world, so don't have much knowledge about digital audio.

I actually want to stream audio from Windows PC to Allo Boss. Not just streaming using DLNA but all the audio from Windows PC to Allo Boss, like we have it for Mac's (Airplay). Is there anything similar for Windows PC?

I am using Allo Boss with PiCorePlayer installed.
