Band: opinion spread · Dot: weighted average
The record's central argument, and it is a measurement disagreement about interpretation rather than about facts. Every rig finds the ear-gain peak sitting near 3.5 kHz instead of 3 kHz. The larger camp hears that as a character trait — vocals rich, timbre natural, nothing fatiguing. A smaller but well-equipped camp hears the same shift as a slightly coarse or thin voice that is measurably less natural than an HD 600. Both camps are describing the identical curve.
Measured
Four rigs, one finding. Resolve measured it on a Brüel & Kjær 5128 and a GRAS and calls the shifted ear gain the key feature to note. Kuulokenurkka, on a clone IEC-60318-4 coupler with KB501X pinnae against Harman 2018, puts the response peak 'slightly later at 3.5 kHz, and somewhat accentuated'. SoundGuys' own rig reads a narrower spike centred at 3.7 kHz. An owner posting his own B&K 5128 traces files the same band as a lower-treble peak. SoundGuys' MDAQS timbre score is nonetheless 4.7 out of 5.
vs. listeners — The interesting part is why the Hadenys wears the shift more lightly than its closed twin, and two analysts arrive at the same mechanism independently: Fc-Construct credits 'a touch of 1.25 kHz elevation that helps to balance out the higher ear gain', and Kuulokenurkka writes that the energy around 1.2 kHz 'likely prevents the 3.5 kHz emphasis from standing out too much', noting the more level Azurys shows the same peak more plainly. So the split is not about whether the peak exists — it is about how much of it your ears, and your recordings, let through.
“This combined with warmth injected by the mid-bass bump gives the midrange of the Hadenys a natural, realistic presentation.”

“There is slight harshness at 3.5 kHz, so the timbre is not perfectly natural”
