I reviewed the ifi nano iOne a while back. Before sending it back and with owner's permission, here are the guts of the unit.
I don't have much time to do a reverse engineering on it. So I will provide the top and bottom images of the PCB and let you all do that if interested .
Here is the bottom side of the unit: (click on the image for full size)
I have marked the main engine: the DSD1793 DAC.
Clearly visible at the bottom is the all-in-one module from CSR for Bluetooth.
I can't see the markings for U500 on the right. And the numbers for the tiny output buffers seem proprietary to iFi.
Assembly looks very clean with no manual re-work.
Here is the top side:
The main item is the XMOS USB interface on a daughter card. Nice to see glue on the connectors to keep it from coming lose.
I also appreciate the CE mark showing likelihood of compliance with European safety and emissions standards.
I have to put the thing back together and mail it now.
