thoughts on MBL amps: 8011 vs 9007's

I have a pair of MBL 111e's being powered by the smaller 8011 monoblock amps; all I could afford at that time. I like my MBL's; but was wondering if my amps are enough to bring out all the music from the 111es. I know people are polorized on the MBL brand; but I'd like some opinions on whether there would be enough improvement in musicality and base response; and flow of the music by moving up in the amplifer line to justify the huge increase in price. Or would a different brand of a high current, solid state amp do the trick for me for less money. I also know some folks here are running MBL 101e's with Lamm tube amps; but I'm not sure i'm ready to switch from ss to tubes; and the hastle factor..thoughts on reasonable upgrade path would be appreciated...economy is making the upgrade bug more of a luxury; but the bug is tickling..thanks for helpful replys.
Setup: MBL 111'es main; Meridian 861 processor; aerial cc5 center; Parasound A-51 multi amp, velodyne dd15 sub; Meridian G-98 source; and Qsonix music server; with MIT Maxum M=2 cables. Large; open room; high cathedral ceilings; wood floors;
