Does anyone have direct experience with this? I've been looking to turn one of my Pi3s into a driver for some in-ceiling speakers I have and an AMP/DAC combo would be great. It would also help to have a diagram of the x400 100% in English to see what chips are used, etc.

EnsuingRequiemI have two, from different sources, and both are quite similar (same chips for eg). I assume this will be similar.
The manufacturer is Suptronics, AFAIK. http://www.suptronics.com/xseries/x400.html
Amp chip is a TPA3118, the DAC uses a PCM5112. Input voltage is 6-24V - I have mine running on old laptop power supplies at 19V and the one driving a set of bookshelf speakers can comfortably fill a room. I assume that to get the maximum rated output from the 3118 you'd need to be running at 24V but I haven't tested this.
It works with Rune Audio and Volumio out of the box (documentation suggests that you choose the IQaudIODAC driver but in Volumio, at least, the IQaudio Pi-DigiAmp+ driver works better with the volume control).
I've got the Pi and Hat in an aluminium project box from eBay/China with hand drilled holes for connectors and the wifi doesn't seem to notice or care.

EnsuingRequiemSuptronics have a newer model, the X5000, that has the same amp chip (TPA3118), but uses an ES9023 for the DAC. http://www.suptronics.com/miniPCkits/x5000.html
You lose the headphone amp, but it passes through HDMI and the volume pot and power switch are connected by cable. The X5000 looks like it's designed to be used in a case, whereas the X400 can be used 'naked', as it were.
Caveat - I've not used the X5000, I'm just reading their press.
