The output impedance of the Ayre preamp is quite low, and will be far lower than, and therefore completely compatible with, the input impedance of virtually any power amp, including the ones you are considering.
Regarding your recent thread about hiss levels, however, the way things were left I would have some concern that after changing amps to one of the McIntosh's you are considering you might still find that excessive hiss is present.
