acoustic music??
ribbon mics. without question. SU-PER-IOR for acoustic applications!
cascade fatheads are awesome, and cheap(300 for a pair) and leaves you some dough to get a nother pair of mics(fwiw, the legendary acoustic/classical engineer/producer tony faulkner uses Rode NT-1s..those are about 300 for the pair too)
OR audio technica 4050 pair..
I say go for something different...something that everyone and their mother on the board isnt using..if noone tries new products tapers will be stuck in a microphone time warp. (kudos to the folks that tried berliners and milabs)..
if you like the sound of breaking glass, go for the km184s!
I despise those microphones.
