I think the MV88+ is superior to the MV88. I think the MV88+ thinning out/bleaching the sound a little bit, but not as much as did the MV88. The MV88+ is what we all should be doing these videos with.
I think on "Eleanor Rigby" the difference in resolution between the MV88+ and the iPhone mic is striking. In comparison I think the iPhone mic sounds like it was dropped in a bag of cotton before the recording began. My other feeling is that, on this track, the iPhone mic inaccurately and unrepresentatively warms up the tonal balance, and smoothes out the sound. On the other hand the MV 88+ is slightly thinning out the sound, making it sound, to me, like Boulder on Magico.
The sound on the videos from the MV88+ has a patina of digital dryness and a bit of an edge of sharpness compared to what I am hearing in the room. But, overall, I think it is superior to the iPhone mic and more representative, certainly of the resolution I'm hearing in the room.
I believe the MV88+ is the mic on which we should standardize.
