I doubt that a brighter amp would help, but then again, this is a pure guess, particularly because you never mentioned the amp you are currently using.
I would consider adding a supertweeter, something like the Elac, which has an omnidirectional dispersion pattern that would fit with the Ohm speaker.
The other alternative would be to get either an equalizer or a linestage with some form of tone control.
