i think its better the waves L1 or the ultramaximizer (my experience tells me it works better, and it has better controls), before you apply anything check the level's of the track with the inspector(free demo vst) or something like an analyser then just apply the right level, i manage to do a very good polish of a track like yours this way. You can also render the project to cubase at 24bits 96khz and then just take the freqs under 20/12hz just in case its too muddy and then apply the maximizer.
