Advice regarding digital Bluetooth receiver

Hi Gents and Ladies,

At home my system is a KidNAP feeded by a Schiit Gungnir .

My girlfriend and I tend to use Google Music quite a lot on the phone. At the moment I'm bypassing the Gungnir, and playing directly from a Shox Bluetooth receiver which works quite nicely, because the 'remote' is portable.

Can anyone recommend a Bluetooth audio receiver that has a digital out? either optical or spdif which I can send through the Schiit dac?

Or perhaps something completely different?

Thanks,
Rudolf
