Purchased a Hermes directly from Denafrips.
When feeding it a USB signal, my Mac recognizes the Hermes under "system preferences." However it doesn't send a signal to my DAC via optical or coax. Other digital inputs work on the Hermes, just not the USB.
Like I said, I have a Mac so no driver needed as per Denafrips instructions.
I sent an email to Vineshine.
