If you've got the dough, Focal & Audison are great. You can buy more inexpensive amps and still get just as good sound (especially in the car): Alpine, Boston, JL, Rockford; typically at 30-50% the cost of those expensive amps.

I'm not too familiar with Sound Ord amps. You say you want to upgrade, but don't really indicate why. Something you don't like about your setup? Seems to be installed and working fine...
