thanks ... all in all i ordered it and planning to use the eq and clear bass options .... all what i am caring about is its treble ... as i used F806 before and that one had king of metallic and sharp treble which i didn't like ... hope that the new A series is different ..
does it benefit from burning in for its POSCAPs or what ?
I have not heard any effect of burn-in on my A15. The treble is a bit grainy, though I won't go as far as calling it metallic or sharp. It is pretty normal for DAP of this level to have slightly grainy treble and A15 certainly isn't better or worst than its class.
