Amp/Preamp combo for Wilson Sophia 3's

I've been thinking about upgrading my electronics (amp/preamp) from my current Ayre KX-5eMP and VX-5e. Been thinking of the Ayre KXR/MXR combination, but my dealer says there are better combinations for the money. I recently heard Wilson MAXX 3's w/Boulder electronics (2000 series I think) and was very impressed, so that's an option. Any others?
TIA,
Tom
