I am interested in the iBasso DX50. I had a Fiio X3 but it stopped charging in the middle of its charge cycle and ended up not working even when plugged in. The only other source that I have is an iPod Nano. So how good is the build quality? Can I use it while it is charging? And finally, can I use the microUSB cable to connect a DAC? I have ordered a C5D DAC/amp and would like to use the external DAC. But if I cannot, then I will hook it up to the line-in of the amp part.
The DX50 is cleaner and more detailed than the X3.
