Friends.
I came here to share with you my findings to improve the sound of the DAC-x6.
Firstly, I must inform you that several units of the dac-x6 are coming from the factory with the defective P10 adapter, it makes the sound sound bad and with the bass loss, I changed my P10 adapter to another better one and woooo !!! Better and better definition before I forget I also connected the 12V 1A power supply to another better 2.5A quality 12v which was the best thing I did the DAC-x6 is another dac now sounding much better.
Sorry for my bad English. I'm from Brazil.
Then post some photos.
Thank you
