If your mixdowns are lacking a bit of tension or emotion, the Magma Stressbox Software Plug-In from Waves can offer a greater amount of control and emotional/energetic injection through compression, size and shape manipulation, and limiting.
Turning the main knob clockwise from 12 o'clock adds aggressive compression, bringing the room sound to the forefront while increasing punch and drive. Turning the knob counterclockwise from 12 o'clock expands and enhances transients, tightens up the general mix, and controls reverb tails. Lackluster and flat recorded tracks are brought back to life with motion, punch, and presence.
