#472 Campfire Audio Polaris Discontinued eBay
Pros: Measured response gives it a solid Harman preference score of 70 with a 2.13 dB spread. Bass is lifted about 3.6 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. It uses 1 x 8.5mm dynamic + 1 x balanced armature with an easy 16.8 ohm load.
Cons: Discontinued, so it is mainly found used. An 8.2 dB peak near 7.9 kHz can make cymbals and sibilance sound sharp.
