Maximus will deliver transparent peak limiting and volume maximization without coloration of the processed sound. Maximus excels equally well as a final mastering plugin or as a per-track effect. Lock and load.
Maximus is a unique hybrid between a mastering suite and track effect, straddling the line without really throwing all its eggs into one basket. Sure, it's not full-fledged enough to replace a mastering job by a pro, and it's not the best limiter/compressor out there, but when used judiciously, it can smooth out a rough mix like a charm. "Judiciously" is the key here, because Maximus is not above taking your frequencies and mangling them if overapplied- especially in a more delicate or finalized mix. ...Manually drawing envelopes is grand as well. Oh, and you can crank this thing to loudness wars levels, of course.
