#364 EarAcoustic Silver Angel SPA Limited Edition: $565 eBay
Pros: A single 11.4 mm titanium dome dynamic IEM with a preference score of 76, full sub bass and a warm 3.7 dB upper bass lift. The midrange stays within 1 dB of target, and the 2 pin cable is detachable.
Cons: A 7.3 dB peak near 8.2 kHz can make sibilants sharp. It is a limited run sold mainly in Japan at about $565, and the score rests on a single measurement.

Frequency Response
How the EarAcoustic Silver Angel SPA Limited Edition measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is a single measurement, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: a single measurement from the squig.link database of practiphile. Thanks to them for publishing their work.
