Campfire Audio Andromeda Measurements General discussion here: http://www.superbestaudiofriends.or...a-holy-cow-this-is-a-dream-awesomesauce.2075/ Campfire Audio Andromeda Frequency Response (0db REL = 100db SPL) Resonant peak near 8k is a measurement artifact caused by the coupler. Take anything after 8-9kHz with a grain of salt because of the limitations of the coupler. Campfire Audio Andromeda Distortion (at above FR levels) Campfire Audio Andromeda Impedance and Phase (electrical) Note: There is a 20 degree phase shift at 20kHz (starting at 10kHz) and 10% impedance roll off at 20Hz (starting at 50Hz) inherent with the impedance measurement apparatus. When I have more time, I'll build a proper system for this measurement; but the current results should still give us the gist of things. Impedance measurement seems interesting. High output Z amps will make this IEM sound bright. I will follow up on the effects of output Z to validate. P.S. You know this has to be good when I making excuses to keep measuring every aspect of it so I can keep it around for as long as I can.
