We might be able to push it higher (maybe 30k) with some trickery, I've not tried. No promises ;)

Wow, Hugo, now you've got my attention. You'd get enormous publicity if you were able to get self adjusting equalisation into Emma (and/or her home equivalents). Recently, a couple of home amplifiers were introduced that included that capability. I can't find the issue of the (German HiFi/High-End) magazine Stereo right now that ran an article on them. I'll hunt some more and will send you a copy if you're interested.
