Want it louder, but not kill the dynamics

[leddy]

Another trick is to double the track, and use a compressor to smash the double. Really slam it. Then mix the smashed track back in with the original un-compressed/un-limited track.

A book that will be of great use to you in this process is Bob Katz's "Mastering Audio". Worth every penny.

Bob explains this technique very well in the book. If you think of compression lowering the peaks, think of this as upward expansion raising the more quiet passages. It is a way to "compress" without doing as much damage. Transients are more preserved, etc.
