At this moment I am using:
BIAB with the "Coyote DXi" plugin.
Forte Ensemble.
ArtVista Grand Piano VSTi.
M-Audio "Key Rig" VSTi.
M-Audio Axiom 49 board.
Couple of other things.
Sound quality through my M-Audio 24/96 is more than acceptable!

You are right, having the classical and other non-"modern" music in the program is a master stroke. And when you add in the thousands of BIAB songs/styles that exist for downloading on the 'net, it is really a great package. I am learning, learning -- using the BIAB piano parts (comping, etc.) for instance. Something I have had to learn from scratch.
What a blast this is.
