So here's my video of my tests of the Mic Pro vs the Sennheiser MKH 30/40 MS rig, which costs about 30 times more. And it is massive in comparison. And takes a fair bit of setting up.
- I don't make money from my channel.
I incorporated relevant frequency plots in the video rather than clutter this discussion with them.
Overall, to my (elderly) ears, there's not a vast difference between these two rigs. Certainly less difference than there seems to be between the Mic Pro and other low cost portable 32 bit float stereo recorders with built in mics I own. The chief difference is probably due to the inherent difference between MS audio and 'normal' audio.
It seems to me that this is a groundbreaking device - but apart from people here, nobody seems to have cottoned on to it. I've not seen other YouTube videos focussed on its use as a stereo recording device - others just see it as a another wireless mic system only for use with video. Oh well. Time will tell.
