Warning: Spoiler! (Click to show)
Just wanted to share my progress on perfect fun sounding he-400 to my ears.
Amp/DAC used : Schiit Magni, Schiit Modi
Exported preset for Electic-Q
27.2 HE400.zip 1k .zip file
With this EQ I can hear instruments more forward instead of "behind doors", vocals are much more preset, can enjoy/feel close sounding guitars nicely ,can focus on whichever instrument I want ,bass is great as always with little boost and I got no problem with treble at all me with this.
For me it's few steps from finished cure to he-400 imperfections.
Would be great If anyone of you guys could try it out and tell me some feedback
I think I am nearly done.
Of course maybe it's total crap, you have to tell me
I'am working on this by my ears and some graphs Jerg posted already, which helps a lot - I can see where to start.
ps: oh, forgot to take it under 0dB, well was listening to this about 3 hours in row and didn't experience any clipping so guess it's fine like this too.
That's too aggressive of an EQ, in my opinion. Try this instead:
Drop 20 Hz - 1kHz evenly by 4 dB, then have a steady straight slope upwards from 1kHz to 5.5kHz going from the -4dB level to 0dB level (5.5kHz will be the peak of the whole EQ at 0 dB), then a sharp but still straight slope down from 5.5kHz to 12kHz going from 0dB to -8dB, followed by a slope back up to 0dB from 12kHz to 20kHz.
