Neither EE DAC will work with the USB output of the Touch using the EDO app.
The MiniMax DAC USB receiver chip is limited to 16/44.1.
The MiniMax Plus DAC uses the Hi-Face chips and software that is not compatible with the Touch at this time. There may be an update to the app to allow this work at some point.
The SP/DIF inputs all work with the EDO app for the Touch. There might be some trouble with 24/192 on the MiniMax DAC, but 24/176 works absolutely fine.
