Lots of "misinformation" going on here of people that clearly never owned maggies.
You do need a good amp to run them, and I do mean high current. In terms of impedance, they are actually less of a load than a point source (cone) driven speaker by a large margin. They are low sensitivity hence love power !
People tend to forget these are speakers that have a laid out voice "coil" and not a coil winding. Then we get into the far superior ways a maggie can sound over any box speaker.
Dipole, line source, no coloration of cabinets, there is not much out there that beats a esl or planar on accurateness. No cabinet coloration, however they lack dynamic low end. Subs are highly recommend! Once dialed in and set up right ?! They can handle stupid amounts of power.
I can tell you tons of good stories about maggie's I got 4 sets aside from the cone speakers I got. I will never give up my maggie's for any box speakers.
None of them will produce the sound field my maggie's can not even close.
