Band: opinion spread · Dot: weighted average
Sources split three to one. The larger camp — Super* Review, Resolve, Hangout.Audio, Prime Audio, McCullough, SBAF's shotgunshane and most owners — hears a warm, dense, 'new neutral' that is the Hexa done more maturely, and reaches for the HD 650 comparison again and again. The smaller camp hears the same tilt as too much: 'too warm' (Gizaudio, 3/5), 'very boring and dark albeit safe' (Precogvision), 'dark and muddy' (an ASR owner who resold it), a regret-thread 'too warm' and Reddit's 'underwater'. Even its tuner calls it 'a little bit too warm for me in the mids'.
Measured
Thirty-seven IEC-711 rigs (500 Hz-normalised) agree within a decibel below 5 kHz: 2–3 dB under Harman IE 2019 in the sub-bass, 1.3 dB over it at 200 Hz, an ear-gain peak at 3 kHz that is 4.3 dB under target, and the whole 2–7 kHz band 4.5–7 dB under. Against the Hexa on 28 shared rigs: the same sub-bass, +1.6 dB at 200 Hz and −0.6 to −1.0 dB at 2–3 kHz relative to 1 kHz, and 3–5 dB less at 8–12 kHz. Three B&K 5128 rigs show the same shape.
vs. listeners — Both camps are describing the same curve — a Hexa tilted about 1.5 dB toward the low mids with the presence region well under the Harman target. It reads as 'natural, speaker-like' to listeners calibrated on headphones and as 'veiled' to anyone used to Harman-style ear gain. The one outlier reading is Prime Audio's 'light V-shaped' with '3-4dB from the sub-bass', which the shared-rig difference does not show.
“this is definitely a warmer, denser version of a neutral sound signature, but still very much squarely in the realm of neutral.”

“That sound signature is just way too warm for me in the mid-range.”
