#228 64 Audio U12t: $1,999.00 64 Audio eBay
Pros: Twelve balanced armatures produce a warm, smooth tuning with sub-bass right on target down to 20 Hz and about 1.6 dB of extra bass for body. In the median of 22 hobbyist measurements on squig.link, the treble never rises more than a fraction of a decibel above target between 1.5 and 12 kHz, so there is no harshness or sibilance at any volume. At 108 dB/mW it plays loud from a phone. It matches the rating of the SoftEars Cerberus for less money.
Cons: Presence sits about 5.7 dB below target from 3 to 6 kHz, with a 7.9 dB dip near 3.3 kHz, so vocals and guitars sound distant and detail is subdued. The 64 Audio A12t from the same maker rates higher at the same price, and the Fir Audio e12 matches its rating for less.
