you will significantly improve your balance between speakers by using one brand/model amp for all speakers. Each amp, even different amps from the same manufacturer often respond differently to different level input, and as dynbamics change, so will your balance amoung speakers.....
I used to have different amps, then went to similar amps from the same manufacturer then all the same amps and it really does matter.
Just my 0.02.
