So.... I ended up buying the M23 microphone. Using HQplayer, I was able to save both convolution files from each microphone, and compare them on the fly, and switching back and forth instantaneously.
Could I hear a difference... YES.
Does the convolution file from the M23 sound better.... YES.
Is it enough difference to justify the cost...... Probably not, but I didn't want to go back to the Sonarworks. I've heard bigger improvements from cables. I bought it at a retail store that allowed me 30 days and I could return it. But decided to keep it.... Cause of the small improvement and I suppose, peace of mind that I'm using very high quality microphone.
It's mainly improvement in imaging, and possibly better tonality, but that one could be in my head, it's that small.
I took a short video of the measurements being compared back and forth.
