Your amp is probably putting out about 100 watts into the Omens, which is plenty.
I am not surprised you did not hear a difference with the snubbers installed. Omens are not that picky about amps. The purpose of the snubbers are to flatten the impedance curve of the speakers and reduce the impedance the amp sees.
A couple scenarios where the snubbers are useful:
1. Speakers are heavily damped and the amp has a high damping factor and bass response and impact is suffering. Typically you might see this with the 16 ohm Zu models.
2. You're using a low powered amp that likes a flatter impedance load.
As far as getting the most out of them, if you enjoy the combo of your amp and the Omens, I'd play around more with toe-in, floor gap height, etc.
