I made the promised measurements. I used the MMM method, so please do not overinterprete small differences between measurements. I am not competent enough for a proper review or comparison of microphones, so please take it as it is - my amateurish measurements as best as i could. I always measured L+sub und R+sub and then made an average of the 2.
As input devices i used the MA-1 (uncalibrated) with a MOTU M4 vs. a UMIK-1 (individually calibrated by the dealer (hifi-selbstbau.de, if you wanna know). Output device is a RME ADI-2 DAC in both cases. No smoothing. If you ask me i would say they are practically identical, if you consider i made those with the MMM-method.
If all units are like mine, my understanding is that this shows that the MA-1 can be used without calibration for room EQ-purposes without any concerns.

Additionally and off topic, again the effect of the 2 PSI AVAA in my room which are at the back wall. Pretty much the same as in earlier measurements i posted.
Tiny improvements between 80-150Hz, much more effect around 25Hz (could be SBIR from back wall). Edit: just for clarification, i am only talking about dips. The elevations around 34Hz and 68Hz would have been flatted out by the MA 1 if i had done the room eq measurements without the AVAA. So i am showing the end-result of the measurements with AVAAs active vs. simply AVAA switched off afterwards. It is not meant as a serious evaluation of the capabilities of the AVAA, only a "quick and dirty" impression.
