I also tried it out with my Fiio M7 Dap and I didn't have a issue with it as the Q11 worked right away without any issues. Over all the Q11 came off as being invisible in the chain if that make sense as I heard the sound signature of my ER2SE being flat and the sound signature of my Pro500Mk2’s having no brightness just some small details and a lot of bass, and finally with my sundara connected to the 4.4mm sounding really good with the highs having right amount of detail while not being blight, feeling of a large sound image with the music being as if its outside my head and the bass having some impact behind it. You really only notice it if you’re pairing a high sensitivity iem with the Q11 such as the CRA CCA or Fiio EA1 etc. There is some channel imbalanced but it really only happens at ultra low volume, volume setting you turn to after you turn it on but after you raise the volume more it goes away.

Then the second page of it explains the Q11 and what each of the earlier plugs and knob do.

Also you will see the different dac filtering settings by default its on non over-sample filter. In the app you will see options such as switching the 3.5mm from Headphone to spdif and then either enabling the RGB LED or disabling it.

On to the spdif support that I mention before, while there is windows drivers which enables the use of ASIO, the settings isn’t accessible thru the xmos control panel, but the Fiio control app in android, meaning you have to disconnect the Q11 from your PC and connect it to an android phone, (Iphone users is outta luck for now since Fiio Control app in the apple store doesn’t support the Q11).
