Broken,
Jfrech is one experienced guy, and sounds like he has actually done what i was suggesting with your amps. FWIW, i also have spoken to a former BBC engineer about my old CJ MV60s (55 watts/channel) when i was thinking of how to get more juice, and his description of what would happen exactly matches what Jfrech just described above...way, way better in all ways...more power, more control, superbly better bass damping, fuller soundstage, better macro and micro dynamics...
one to consider given that it sounds reasonably straight forward to do.
