Simple question, and I really hope it doesn‘t sound rude, but what happens if You adjust the frequency response to Your personal best liking with an equalizer? Removing the peak should be possible in case it stands out.
It is ment as an argument against Your point. On the other hand I‘m curious by what means the peak would be accessible. I couldn‘t make it with any confidence.
E/g, when exaggerating something that high it didn‘t feel, tested with white noise, like a resonance, like it easily did, say at 5kHz. It made more shine, to come to glare it needed 10+dB the least, but no feel of resonance still. Any suggestion, and sure, my hearing is not pristine?
