I'm not a big fan of "counter-balancing" the system. For me, it usually becomes "not really good at anything."
I think you should set your musical priorities and find components that more or less rides along that line so it will become more of an issue of "sacrifice,", not "compromise."
If you find the MA's too bright don't try to balance it out. Just find different speakers, and then matching electronics that support the strengths of the speakers. It takes time, but it will happen, eventually.
I think you could look at this another way and say that every component has a sonic signature, and some work better with various components than others.
