So,
It likes to crash on device settings. Not always. Not sure if there is commonality to the crashes.
The list of devices is largely insane and the options make 0 sense.
Theaterview likes to be somewhat unresponsive at times. Not sure what is happening when it occurs. It mostly doesn't do this. Just every now and again. I did just import 9000 files on a mobile 2.5" HD that is about as big a slug as there is. So, you know, maybe that has something to do with it.
Takes like 30 seconds to close.
Otherwise it all works and sounds great.
As an aside if you have a DAC running on the edge or, rather just over the edge, of the USB power output putting it on a USB 3 port will make life much better as it is like 900mA instead of 500mA.
