Sounds like you are going plenty loud off a pair of stand monitors so more power may be moot but more current may still be a ticket to better sound.
Two potential issues with trying to go louder:
1) the old heat/compression factor that could make it a moot point
2) the damage 100db + will cause to the ears over time if used regularly
In my case, I wanted my system to not be a limit to how loud I go practically and achieved that. But now as with any dangerous weapon (to your ears) one must be careful how they use it.
Also if phase/impedance curves for teh minis are available and show dips/issues at lower frequencies, setting up teh crossover to have teh powered sub address those and not the main amp should help alleviate any current bottlenecks. Remember that power requirements increase exponentially at lower frequency so as frequency goes lower the drain on teh amp increases not linearly but logarithmically ie a lot! AMps do most of their work producing bass. WHich is why getting bass under control in the gear first is so important. You always want your amp to not have to work any harder than it is designed to do and manufacturers will exaggerate that ability often for fear of limiting sales. No amount of room treatments can fix that issue if present.
