Is it not an option to just run HPF in post? For seriously loud shows the 4060s can overload... I have a pair of 4061s for such occasion
The at853s are good, but not in the same league as the dpa406x in my opinion. (I used to run es943s, which are sonically similar to the at853s).
I run the same mics, and I'm seriously considering a pair of 402x = very nice cards, and keeping with the same dpa sound. Of course that's serious $ which I can't really afford right now. If your budget will stretch that far I'd seriously consider those.
Oh and thanks for the damo btw
