I have #3 & #4 Black Diamond Racing cones and I don't prefer them on their own. They do some amazing things to the sound as far as soundstage and details go, but I've found that they also have some disadvantages that come with the benefits. Everything seems to be more detailed, but that includes the vocals too. They become too detailed, and they lose their warmth. Sibilance and micing problems really stick out. That's just my opinion. I put some sorbothane underneath the cones (at the tip), and that seems to be a good compromise (for now).
Like I said, they definitely make a difference, but they seem to require a lot of experimentation. Just a warning...they may drive you mad.
