Campfire Solaris IEM Measurements

I did these really quick, so subject to future revision

Campfire Solaris Frequency Response

1. That 10kHz peak is false and a result of the silicone tube coupler, It's just not what I am hearing and this coupler isn't that accurate past 8kHz.
2. There is more diffuse field EQ compared to Andromeda, but in the overall scheme of things it's still moderate.
3. There is less measured bass than the Andromeda. I think this is true and partially reflective of what I hear. The DD bass drivers do seem to present more bass than is measured.
4. Out-of-the-box without tweaks or mods or tip rolling, the Solaris sounded just fine from a variety of sources.

Campfire Solaris Impedance S

Still reactive, but much better behaved than Andromeda where the curve jumps to almost 30 ohms. Nominal impedance just a hair below Andromeda, and likely accounts to why I felt there was a touch more hiss with some sources like the Sony ZX2.

Campfire Distortion Measurement

I thought there would be a bit less 3rd order and more 2nd order. Overall THD (sum of harmonics) is lower on Solaris below 100Hz. There is more 3rd order from 100Hz to 1kHz and more 2nd order in the mids compared to the Andromeda.
