could someone recommend some good acoustic music

in which to test klipsch speakers? I've read several post that tell of a harshness with horn speakers when it comes to acoustic music. Either you'll like them or you won't. I've only heard them during home theater use, so before I buy I'd like to hear how they sound with something that brings out their weakness (in some people's opinion) I go for more H/T, but my better half is more into music.
