I have run my Extremas with many different amps. A forte, a very small Musetex,and Dual Classe Ca 400's that I run with MIT Push Pull cables. I can tell you that they sounded very good with any of those amps. They like a lot of power and the more you have the better they sound but you can drive them with just about anything.
The reason they like the power is something to do with the crossover. I think it doesnt use compacitors but I could be wrong.
