Both choices are good one specially if you will use them as combos: Boulder 1050/1010 0r 1060/1010. Viola Symphony is stereo amp but, you thought about using it as monos?
Well, I will not recommend that. Stick with single Symphony, it has enough power for MaxxII. Viola Symphony/Cadenza combo is very good one but, IMO Boulder are better(only new Krell Evolution's are in the same class). I audition Viola's only at audio show and they sounded to cool for me. I tried Boulder 1060/1010 combo with my former speakers(W/P7) and it bettered my Ayre V1x/K1x(also sold!) combo in every respect.
