Fiio KA15

In stock form, the KA15 is neutralish, but of course the PEQ above unlocks whatever tonality you wish for, which increases versatility. Desktop mode seems to provide better separation, imaging and soundstage compared to non desktop mode (even after volume matching), but this comes with more battery drain as a trade off.

I don't hear any hiss even with high sensitivity IEMs, though there is a disappointing pop on inserting or removing transducers from the 3.5 mm port. The 4.4 mm port is better implemented and remains silent when connecting gear. The KA15 has <0.8Ω output impedance (OI) on 3.5 mm, and <1.2Ω OI on the 4.4 mm port, so it synergizes well with fussy low impedance IEMs.
