Well, the Oratory & Amir rigs (GRAS) are effectively the same as the original Harman rig. The pinna is not exactly the same as apparently Harman used a custom made pinna, but the rigs that Oratory/Amir/Crinacle/Resolve use are all GRAS rigs that are the current best thing in terms of a legitimate "Harman Rig". I don't know how much actual difference you would see in measurements using the original Harman pinna vs the current one used on GRAS, I have a feeling that the main difference was just the flexibility of the pinna, the original Harman pinna was stiff, so I'm thinking the GRAS pinna used mimics the Harman one but is more flexible (increased pliability/malleability) and therefore more like a real human ear in terms of better headphone fitment but someone can correct me on that if they for sure know the differences.I wonder how much of these differences in target curve preferences are actually a merely function of differences in the measurement rig used to create that target?
Let's say Harman created headphones that precisely matched the Harman-target measured on a Harman rig.
If you then took those same headphones and measured it on the Oratory rig, it would measure different. And Oratory would then issue EQ settings that supposedly "correct" the headphones so that they match the Harman target. But in reality, the headphones with 0 EQ are, by definition, are matching the Harman target.
