The Spectron Musician III SE is the way to go. That's what I have driving the Maggies 3.6. The Spectron will bring lots of detail and control at both extremes of the frequency range. It produces a very refined sound, reminiscent of much more expensive gear. I tried a few other amps with the Maggies and the sound was kind of flat with all of them. The sound with the Spectron is very 3-dimensional and articulate. This is a very transparent amp, so it will show the strengths and weaknesses of the other components in your system.
