I've had good success using autoformers with Maggies. It's actually not a tough speaker to drive if the low impedance is removed from the equation.
McIntosh SS amps are a great match because they already include autoformers.
Otherwise, you can get Paul Speltz autoformers and then use countless other amps with great results. On a budget, I'd recommend a used McCormack which would be better than 90% of your options in stock form (or you could always get it modded for SOTA performance).
Tube amps aren't quite as beneficial because you don't need voltage swings as much as current, but ARC amps sound great with Maggies if you prefer a tube sound.
I've heard the Magtechs and they sound fine too. However, I think a lot of the "hype" about them being ideal is over blown. Lots of tube and SS amps are more than capable of driving these speakers.
