As a core professional music player, the Decoding Chip, the Fiio M6 is also a bit sloppy, using a mature ES9018Q2C decoding chip, supports 10 segments of EQ free set , and has 120 levels of volume adjustment. In addition, the M6 also supports LO output (shared port with PO), but it is a slight regret that there is no 2.5mm balance outlet.
