Hah, right, I mixed up filtering as such with the cutoff frequency of
bass boosting. And probably this is related to the mentioned high-pass
filter effect of the talked resistor which is why the boosting is
required in the first place to counter that. Too many mixer settings,
and definitely not an audiophile's dream :)
