there are many many solid state amps that can deliver strong, ample current into low impedance loads - which is what is needed to drive maggies to appreciable volumes
maggies are also quite revealing so the input signal and power needs to be very pure, or else the maggies (like many very transparent speakers) will play the bad sound for you to hear, not smooth it over
so, the key is to get a powerful well built high current delivery amp (in all likelihood solid state) that sounds super clean super pure - there are still many out there that meet both criteria, but they are fairly expensive
