Sorry for the double post but is for a good a good reason: my first hi-fi DAP (I used DAC+AMP devices), I'm very very happy with this player
Zero bugs until now, tried the last 3 FW and I'm happy with the last FW (it's not boring at all, 1.3.3 is more boring because is fuller and has less treble presence, I prefer much more 1.4 as it's more dinamic), I noticed that they are improving small things also in menus for better visibility and usability (stuff like transparency also - like in volume), good UI, really great player! I use the Earsonics SM64 V2.
I have to say, these guys are no rookies in this, well done iBasso, nothing is out of place.
Very Hi Fi and clean sound!
