I have tried the MW200 with couple different pair of IEMs. The MW200 is more than sufficient for the low impedance and high sensitivity IEMs and it drives those really well.
It pairs great with my Andromeda Gold/Andromeda S/Andromeda 2020 and fairly well with the Ibasso IT01s as well.
However, the MW200 will have trouble with harder to drive IEMs (eg BGVP Zero) and seems to struggle to put out enough power to drive them well. The BGVP Zero has thin bass and thin treble when paired with MW200 even at max volume. But USB dongles have no trouble driving the BGVP Zeros to their fullest.......
