I did it properly, the firmware upgrade was succesfull and dac is properly working with the new firmware.
Thank you again for the marvellous device, it sounds amazing in my system, awesome musicality and rhythm, detail, really a great designed product for a bargain price. Very nice job! I guess you are selling many of them because all the reviews are so enthusiastic.
