Hey, I just wanted to report what I suspect is a bug with the AudioFuse 8pre firmware.
It's connected to my iMac via USB-C. After both units have been on for a while, it appears the 8pre sometimes stops working. A workaround is often to power cycle the 8pre. However, it has some interesting side effects, for example it prevents YouTube videos from loading. The connection to Logic Pro is also a bit weird sometimes, where certain audio tracks will just stop producing audio until a restart.
Sorry I can't provide more detailed information.
Dave
