Thanks Curt, David, Paul and Rob.
Some great info to mull over. I am waiting on the AT4022's to arrive, once =
I have them will build a rig to accommodate them.
Paul, in listening to the side by side comparisons between the AT3032's and=
 the MKH-20's I felt that the MKH-20's with the SASS rig delivered a fuller=
, richer sound. At least to my ear. Now whether that can be attributed to t=
he differences in the rigs, or the quality of the MKH-20 microphones themse=
lves, I am not qualified to say. I might add thou, that if I had only liste=
ned to the AT3032's I would have been more than happy.

Cheers,

Paul
