BLUETOOTH Streamer for ARC CD9 DAC but using AES/EBU on XLR, or USB inputs


I am using an ARC CD9's DAC as my audio hub.
1- Raspberry PI Allo Signature Roon endpoint to RCA input for PC music library streaming
2- Still have Sonos connected to Optical input to access XM Radio

Now I would like to add a bluetooth devise like Audioengine or other entry level device so my son can stream to the DAC from his Mac or iPhone.

AES/EBU on XLR, and USB are the available inputs
