At least for the Arcam and Parasound you are picking amps in the "warm" sounding range, which is kind of my preference as well but you may want to listen to something radically different as well, depending on your budget.
If you are coming from a Mc, this may be just what you need. I'm not sure what your power requirements are or budget, but I do suggest you consider a tube amp as one of your listening choices as well.
