2 - After i plug the 3.5mm in the DragonFly to converter for usb.

3 - Finally, i connect the pendrive in the usb.



Can i do that to have better quality of my musics to listen in w205??
Or this will not work??


Thanks!!

 

Very unlikely, since DAC use requires software driver at the host end. The Benz software probably only supports FAT32 as a recognized mass storage format so you can read the files on whatever device you plug in. I'd be very surprised if they extend that to include Audio DAC capability.
