Here are My concern about this DX80:
1. DAC mode, whenever I plug it into my Mac comp, always come out as card reader. There is no button to change to dac mode. I need to unplug, change to dac mode on usb setting, and then replug again to computer. Not practical for user. It will be great if we can change the usb mode without unplug first and without stuck at card reader mode.
2. Some of album/song artwork showing pixelated picture. Even tho I changed the artwork resolution and big or small file image. As an art director..To be honest, I feel disturbed about this problem and irritating my eyes to look at. I don't know for other people about this issue.
3. I'm pairing my DX80 with amp. Connecting with line out output. Installed new firmware.
For portable amp: sound amazing. But, when the music playing, sometime or often the song like paused/lag/delay for split second. Tried using other interconnect, different files of song (MP3, flax, wav) and it still there. Reformatted the sd card and factory reset also the problem still there.
For desktop amp: the volume sound is so weak. I tried using headphone out, still weak also. Weaker than using portable amp. Is it the line out still not stable yet?
