A few comments:
1) Power- For these speakers, at a 12 foot listening distance, 10 watts gives 99 db, 25 watts 103 db, 100 watts 109 db, and 200 watts 112 db. The OP said he mostly listens at lower levels, where 10 watts would be more than sufficient, but if he wants to turn it up, perhaps to listen to an orchestra at live levels, 200 watts will keep him from clipping at the peaks.
2) Totally personal, but for me of the three amps, it is a no brainer, Pass Labs. I always found them wonderfully transparent. I liked older Mark Levinson, but they lost me when their Proceed and 331-333 amps started dying early. McIntosh has never done a thing for me, always providing adequate power, but sounding lifeless. To me they are the B&W of electronics.
3) I would be tempted to try tubes with your system. Perhaps something like the Rogue Pharoah integrated with a tube preamps section and solid state amp section.
One thing to keep in mind with Class A amps, high biased Class-B, and tube amps; they all put out a lot of heat and use a good amount of energy. They make nice room heaters in the winter, but depending on your room, could sweat you out in the summer.
