Something about sample A is bothering me. Everything is there, detail and frequency range. It just sounds "thin". B sounds more "rich" if I could say that. I would really need to listen more, but I find A to be not enjoyable. My guess is that B is the Nevatons, but I could be wrong.
There are some other differences as well (EQ, position, etc), but in the end my question is, after listening to 90seconds, which did I enjoy more. I kept forgetting A was music, listening for sounds, not music or individual instruments. I would suggest trying a longer sample, which sounds better after a whole song.
Finally, I think someone should do a comparison of mics side-by-side, on the same hat! I did this comparing capsules in the past (not DPA vs Nevaton), and it is informative.
