there are various tiers of ss class a/ab amps that work well with maggies... all sound very good, drive them just fine, deliver the needed current reserve, some are sonically subtly better, more refined powerful better imaging and space
high value/low cost (below 2 grand) -- ava, odyssey, usher (pass design), unmodded older mccormacks, older primare class a/b
middle tier (2-4 grand) -- hegel, belles, modded smc/mccormack, naim, exposure, new bryston
upper (above 4 grand) -- many here... from pass, psa/bhk, para/jc’s, good krells/levinsons (gotta know which ones to avoid like plague), gryphon, vin rossi and so on
there are others for sure, the above is what i know of, have, have heard at length
