Who the Fosi Audio ZH3 is for
Planar and full-size headphone owners: 2,570mW into 32 ohms from the 4.4mm balanced output is enough for planars and demanding full-size headphones, not just IEMs.
Headphones plus powered monitors: XLR and RCA preamp outputs run powered monitors from the same source your headphones use.
Listeners who like tone controls: Bass and treble EQ is on hand when a recording needs it.
Tinkerers: Six digital filters and swappable op-amps leave room to experiment with the sound.
IEM users: Three gain levels let you drop to low gain for sensitive IEMs.
