Yep, it's the exact same thing I was talking aboutEDIT: And thanks for saving my sanity; turns out I am not crazy, or at least about this particular thing
Hey thanks for the info I didn't think it was an issue but something I had to learn, and that confused me . I played around with a PEQ for a bit and it indeed shows a bump around 2-3 dB from 5K-6K with my parameters; it is from the knee getting harder so the notch and high end I hear is the delta between the top blue line knee and the harder knee. Combine that with the preamp also blocking even more from 10K up and there isn't much difference left to hear except the difference in knee; particularly with old farts whose hearing doesn't go much past 14/15K lol.
Here are some screenshots to show what I mean:
7777.7Hz@ 3dB/Oct: Sounds Dark - less 4K-7K

7777.7Hz@ 24dB/Oct: Sounds Bright - more 4K-7K
