I'm starting this thread because the issue of storage is one of several recurring themes on the threads about the new and emerging high end DAPs from IBasso, AK, Sony, Calyx, FIIO (and any others I have missed).
My only hope is that people will agree and that manufacturers will notice.Things that I would like to see:
more onboard storage
more full size SD slots
USB stick slots (I assume this is possible)
Would love to read other storage ideas.
