hey people of head-fi im buying either the
dt990 250ohm pro
what different amp woud i need to use on them? too get good sound quality. (only buying one of the above mentioned headphones) i like the fiio if this is any help
Any basic Fiio amp will power both of those without any issues. Get which ever one you want. E10, E11, E12, E17, E9, etc, all power the DT770/DT990 fine.
