I have been using his MJE-384K capsules for my Rode NT5's for a few months now. Really nice. A while ago I recorded one of my band's concerts. This is a wind band, about 35 people in a horseshoe in front of the conductor. The mics were behind and above the conductor in roughly NOS configuration.
Very nice results. I had to add about 3dB shelf EQ above 2000Hz or so so make the trumpets sound like trumpets. Took the EQ very well.
I like them.
