I can't find my info for the NT2's, but I can tell you that I have ran almost 1,000 shows with NT2's. I bought a pair of NT2A's last year. After 2 shows, I returned them. They had no life to them. They sounded dull. I ran them on stage next to my NT2's and the NT2's had much more range and fullness to them.
I should also add that I have never had to use the high-pass filter on the mics, so I can't really comment on that part....
