So the choices are:
1. leave as is
2. use crinicle or other
3. mods/PEQ -> ears
I apologise if my post sounded as though I was picking on your reply.
My post was a general post, addressing a school of thought/assumptions championed by many.
It goes something like these:
- PEQ cures a rainy day!
- With enough PEQ bands, setup precisely, any headphone can be cured and made to sound like any other.
- FR curves obtained from reputable outlets are accurate enough to conjure up accurate PEQ settings that would cure all.
These assumptions are just plain wrong scientifically, because:
- PEQ can help with broad tuning of a headphone, no more.
- Every sample of a particular headphone, make & model, is different slightly, and they change as time goes by. Enough to nullify a preset PEQ setting to fit every sample at any age or condition.
- Obtaining FR curves is an approximate endeavour, even using the best test rigs costing many tens of 1000s, handled by experts. The very same headphone sample can yield different results, when tested again and again. slight seating changes, small variations to the pads, shape of the ears used, etc . . . .
- Test rigs are dumb! on an FR test, they do not segregate, distortion or resonances from signal. these would show up as peaks and nulls. Of course a knowledgeable person, would also run distortion tests. Using the two together, he can tell which peak or null is due to what.
On a typical EDXS, I would suggest using a wide bandwidth (small Q) PEQ to correct the 1-3kHz deficiency, that's all.
Depending on individuals, wide bandwidth corrections can also be applied for taste, preferences.
The 4kHz+ and 12kHz peaks are distortions/resonances. By filtering out the music at these frequencies, one would not correct the problem.
Think about it, PEQ only affects the music output to the phones, nothing else.
