Details

The (software-)equalizer is adding high noises to the playback.

I made a recording, the first part with eq enabled the second one with disabled equalizer.

I could also make a test on my older H110, on which I never used the sw-eq though.

Yeah, I guessed this would be a shelf filter issue. I'll have a look at it, but don't hold your breath. And in the meantime you can use peaking filters in the same frequency ranges to avoid the issue.
