I haven't heard those Macs or Classe, but for what it's worth, I love my x250.5 and I personally am not interested in upgrading unless it would be for a pair of Pass class A monoblocks (but my budget prevents that). I'm extremely satisfied with my x250.5.
For the types of music and listening preferences you listed, you cannot go wrong with the x250.5. Overall excellence, and absolutely incredible bass quality when paired with a good solid state preamp.
As for speaker recommendations, that is such a personal subjective choice that you really need to just listen to them yourself and decide. Good luck.
