Thanks for contributing too!
I totally agree that changing one frequency can drastically change how you perceive the others, but I believe this is usually an effect of how we mentally filter and process our senses.
If one recognizes a frequency range and pays attention to it, one can hear that such a frequency remains unaltered even when surrounding frequencies are changed.
To view the frequencies in such a way allows us to break down the challenge of equalizing into much more manageable parts.
Quick update - the peak at 15,000 Hz is off.
I put that in quickly to slightly correct the super highs, but this compensation does not at all reflect what is actually happening in those frequencies.
The peak really needs to be narrowed and have a much higher boost.
For now, I tried 15,000 Hz with +9 dB gain with a Q of 7 and got much better results.
I found this to be extremely apparent in songs with certain percussion instruments such as those in Reckoner by Radiohead.
