Well, I am unsure if I will be scolded for resurrecting this thread, but I felt like commenting.
Thanks for doing these clips. The BN capsule is quite nice, so is the Neumann. The Neumann sounds like a Neumann to me. The BN sounds like a more open capsule. The Neumann has that midrange thing happening that I can't ever seem to put into words. It's a little darker overall, but more intense in that upper mid range. Detailed there. It reminds me of my Miktek C7, honestly, but only in that regard. Otherwise completely different.
The thing is, I feel like I would be happy with the BN capsule in a u67 style build. Finding a real k67 and paying that price is just too much. So might as well use something like the BN to save a bunch of bucks and still have a great mic in the u67 vein. You probably aren't going to be able to build something that sounds totally like a u67 anyway, no matter the parts.
EDIT: I listened again today and gain matched some of the clips a little better I think, and they sounded even closer. What I said above stands, but the gap is closer in my mind. I think when I build a pair of u67 clones I will do BN caps, or one BN and one Heiserman. Lord knows two u67s never sounded the same anyway. I like variety.
Thanks for posting the clips.
