I finally got my RS130 optically connected through the RSA720 USB hub to my Dac, after several software updates to the usb hub, and the 130 bricked today. I am waiting to hear back from MoFi about returning it for repairs. I don’t have high hopes about speedy resolution given the nightmare in dealing with the RSA720 update issues.
Hoping for the best hear because there are few transports that allow full optical isolation.
