#15 SoftEars RS10: $2,099.99 HiFiGo eBay
Pros: A crinacle preference score of 84, and across seven hobbyist measurements on squig.link the response stays within 0.1 dB of target from 200 Hz to 3 kHz, so vocals and instruments sound natural. Ten balanced armature drivers per side deliver a smooth 1.49 dB standard deviation from target. It rates well above the Shuoer Cadenza 12, a rival at a similar price.
Cons: In squig.link measurements sub-bass sits about 3.2 dB below target from 20 to 60 Hz, so the deepest rumble in electronic and film scores is lighter than a dynamic driver delivers. A 5 dB peak near 7.9 kHz next to a 6.2 dB dip near 10.6 kHz can make some cymbals and sibilants stand out while the air above them fades.
