I have finally decided to migrate from my simple mobile phone to a more dedicated source like a DAP and i thought of going for a CAYIN N3 because it says it is compatible with external dac. Price is also pretty good and ships free of charge to my country from aliexpress. I think i can make it work with my FX Audio dac-X6 and HD-6XX using coaxial or usb options. For some reason my xiaomi redmi 5 AI dual cam (Current source) refuse to work with my DAC-X6 on otg mode. all the other phones in my home works. So i thought it is a good time to separate music from the mobile phone. Any suggestions....? I don't know much about Cayin N3 except that some reviews say it is pretty good.
