Though I cannot comment on your particular combinations my testing a few years ago might help. The speakers I was using were the Verity Parsifal Encores, newest version.
Sim W7, great dynamics, excellent "slam", very fast and dynamic
Pass 250.5, much like the Sim but perhaps a bit smoother in the midrange, seemed a bit more balanced, perhaps a bit more air in high range than the Sim but similar detail
McIntosh 402, another nice amp, seemed to draw attention to each instrument but struggled to make them sound well together, perhaps a little roled off at the peakrs.
Classe CA-2200, spend some time with it, very subtle, not as dynamic as the sim or Pass, midrange to die for, very musical. I can see where people say it does not have "slam" as it is more of a musical speaker, very rich, great air, very musical, all instruments stand out like the mac but sound wonderful together. By far the best at getting timbre correct, especially with piano and strings. Definetely takes an audition to choose. I thought that they were all about the same price, (they were 4 years ago) and was pleased to find out the classe was the cheapest of the bunch. If I had to choose #2, it would be the pass for my tastes, another neutral amp, easy to listen to for a long time. Sim and Mac are a toss, but both very nice amps as well.
