What's the output impedance of both the 3.5 and 2.5? and also the crosstalk.

Is this tuned flat neutral or still V shaped like the e10k?

https://www.fiio.com/k3_parameters

1.04 ohms - doesn't say which output. Graphs are included on the page I linked. Essentially flat from 30 Hz to 20+ kHz. Below 30, drops maybe 1dB down to 10 Hz (ie not audible)

Crosstak ≥70 dB (1 kHz)

 

[wigglepuff]

Those graph doesn't reflect the units actual frequency tuning, its just a test graph showing the bass boost gain. Like the e10k which is heavily V shaped with rolled off extensions.
