Thank you so much for posting your eq settings. Have you done any other modifications or pad change apart from eq to your hp's?
Also, when I'm looking at the eq settings, after 11khz, it says 6 khz in the image. (The last set of values) Is it supposed to be 16khz?
I'm planning to take this as the base, and then proceed from there. May I also know which amp you are using with these hps
I have done
no other modifications.
I'm currently using a Corda Jazz fed by my computer. I have also used these hps with a Topping NX1 fed by a (rockboxed) Sansa Clip Zip. The latter is not something I would recommend, but for me it worked flawlessly at the volume levels that I prefer. Generally spoken, an amp
should not have any audible tonal effects except maybe at the very ends of the frequency spectrum. Even then the effect should be marginal compared to what an EQ does. Of course the amp needs to be properly designed and built and able to deliver the power output that is needed without audible distortion. These hps have a very flat impedance curve, so even a higher than normally desirable output impedance shouldn't do much harm.
The boost at 6 kHz was the last one I added, so it ended up on the right side. Due to my age, I can hardly remember what 16 kHz sounds like. Therefore I would never boost the upper treble beyond, say 12 or 13 kHz.
It is very unlikely that my settings will be ideal for you. You will need to use sine sweeps to check for the peaks and dips that
you actually hear. Then of course listen to real music (a variety of genres would be ideal) and play with some values or add some more to find the right tonal balance for you. If you want to try other modifications (like pads), it's best to do these
before you begin your EQ journey or else you might have to start it all over.
Oh, and don't forget to apply negative pregain (-8 dB or so for the above settings) to avoid clipping of the digital signal.
You may also want to have a look at the EQ settings other headfiers posted on this thread and compare.
Good luck! (This is also something you will need...)
