The times where an amp tends to improve the headphone out's sound quality is (1) if the impedance of the headphones don't work well with the DAP and cause bass roll off or loss of soundstage, where an amp could help that - or (2) if the headphones need more power or current than the DAP can supply.
A line out can help you avoid amplifying the already amplified and possibly distorter sound from the DAP headphone out.
Your next step is to acquire a DAP with line out.
