An upgraded to Platinum status McCormack DNA-125 will be pretty darn good. Only rated at 125wpc, but with that Piltron transformer, tons of current and could drive the Maggies very well. Mine is the same w/o the Piltron, and boy does it sound good for what the upgrades and used unit cost.
I also second the Karan! A little pricey, one of the best amps though.
