Mutec MC-3+ USB

[ogs]

I need some guidance here. I had intended to put the Mutec (when I get it) between my QNAP NAS which I believe runs some form of Linux, and my D.  Is this going to work? I have a Mac on the network, will this be all I need to install the updates? 

To be clear, the NAS runs Jriver and will be connected thus:

NAS>USB>Mutec>AES>Devialet

Are you running the Linux version of JRiver directly on the NAS? In that case ALSA is interfacing with the Mutec USB, JRiver is playing via ALSA and your setup should work.

EDIT: Does your setup work directly connected to the Devialet USB?
