Someone should probably rep the AT943E/S in this thread.
They are inexpensive, and a bit bigger than the DPAs.
They have a 3db rise at about 8k - 15k that sounds like female sibilance to me.
If you have a fast and present A/D or Pre, you may find yourself flattening it in post.
Aside from that small response blip, they are amazing performers.
If an occasional very high "swsss" doesn't bother you, you needn't do anything, or if your A/D or Pre is warm
you'd probably be fine as is. I have the cards and hypers for my low-pro setup.
Like I said, amazing performers, great value, however the DPAs would take my vote for best that I've heard.
The limit to me was the availability as omni-only.
I have not heard the Senns. although they have been around in various models for years.
Looking around for them, the first link that I found has them for $125 each:
