The EQ curve is based on measurement and listening to match modified Harmon Curve (basically 5-6db down on the treble response vs target curve). I am using the big bowl pads.

Has anyone needed to make this dramatic EQ adjustment to make HF-2 sound relatively neural?

Completely agree with our large EQ. The Grado treble is notoriously bright and ear-piercing. I wish they would come up with some nice leather sealed pads to boost the bass and bring the treble more in line with the Harmon target.

That said, I highly recommend the yellow pads. They are horribly colored, but they measure the best of all the pads.

See how the yellow pads start to smooth out and tamp down the treble. The square 300Hz wave response starts to flatten out. The G-Cushion pads don't do enough for the bass nor treble.

Do you know where the peaks are? It's best if a rig accurately represents the output so you have an ideal.

The best guesstimate would be peaks at 2k and 10k. Q factor should be grater than 1, propabaly like 3 or so. Try different gain levels, in the negative. Try centered around 8-10k someplace. 2k is pretty consistant peak they exhibit.

So, the 2k likely rises too early, and since 2k and 10k peaks, there is a dipped area in between. You would need to adjust that area as well, if you want somw sort of a target response.

Have you looked at Oratory's EQ profiles on Reddit? It could help.

It would be best if you had a rig to check on what changes occured with your EQ.
