op
as usual, scott (@verdant) provides good input
i would only say additionally that in my travels, i can confirm that maggies are one brand of speaker (atc from the uk being the other) that are seemingly modestly priced speakers, but they are truly highly engineered, exacting (and very demanding) devices that call for amplification that is both very strong/powerful and very good sounding, to bring out the best of the speaker’s ability (and driven properly, they are superb)
think higher end solid state, higher up pass, hegel, chord, and several others scott and others have mentioned - you can go for lower priced, high watt per $ ss amps, but with these speakers, you will hear the ill effects
good luck in your quest for the right one -- it is normal (and necessary) that you drive these sub 1000 dollar speakers with amps that are multiples of that cost - if you are committed to that speaker, you would be doing it right, imo
