Pros: Sound good to fairly cheap price
Cons: Input of music is impossible & the machine has a fever
Sorry for poor English, I'm Japanese.
I bought it at Aliexpress, and it worked fine.
After removing the contents by removing the front cover, PCM5102A there was certainly on the mother board.
And condensers are made by Sanyo.
It is an amateur's impression, but looks like it does not use the bad parts.
Even amateur ear, I felt the sound was better than cheap China DAC(VIA VT1620A, C-Media CM6620) that has been used before.
Music increases the force, I have obtained a clear sense of pitch.
But I wanted a cheap PCM5102 DAC with a input terminal.
I feel unfortunate for it can only output of music.
