You don't need a three hundred watt amp to drive a two ohm load. There are other issues just as important. How large is the room you are using. Is the acoustic enviroment bright or dead? How loud do you normally listen to music. What is the speaker sensitivity. Martin&Logans go down to one ohm and I have heard them driven by quality 100 watt amps. Look for a solid state amp the doubles it's rated output as the resistance is halfed. Also high current tube amps can drive low resistance loads. When in doubt ask a dealer to loan you an amp to try. Good Luck!
