        I (for one) would be interested in seeing the frequency response curves 
for the various drivers.  Are they in PostScript form?

        Hey, anytime Pal, so long as I get to play that juicey C-3/122 of 
yours! 
 And as Al says, A/B eardrum tests are THE only way to go.  You can look at 
frequency response plots till you go blind, but getting the test units 
side-by-side is truely the only way to appreciate their differences.  Trouble 
is, we common players so rarely get enough gear in the same place to do A/B 
tests!  Anytime you wanna line some stuff up Al, say the word and I'll bring 
the 
donuts!
