Has anyone used Xiaxin TV box? How does it compare to TECH TV box?

Xiaxin TV box has a home stereo function, but the price is also more expensive than the general box TV son. For home audio, I prefer some professional, so more optimistic about the Tage TV box, this box is not the same body box and speakers, but in the field of TV box professional degree is very high, the main is high configuration, no lag and no ads, so the practicality of more strong.
