Cool! This definitely comes down to a taste/hearing thing. Having listened to dozens of earphones, and having once owned and rather loved an Audeze headphone, something I realize about myself is that I enjoy having a somewhat laid back 2-4 KHz region like the OG CRA and the EDA Balanced, and having once owned and loved/hated a DT 1990, I actually like a slightly elevated lower treble. The CRA and EDA Balanced walk that line of nearly too much treble without ever stepping over it.

So looking at that CRA+ graph, I see a couple of things I don't like:

1. Increased energy at 2 KHz
2. The somewhat typical 6 KHz dip that definitely avoids sibilance but usually makes things sound kind of boring and muted for me
