Ah, sorry. I misunderstood then. However, I believe the 3 W that you are referring to its the max input power. It is the max amount of power it is rated to handle before running the risk of being damaged. 250 mw should already be enough to bring the mk3 to ear bleeding levels.
The reason it is hard to drive is that it is a low impedance headphone that is insensitive. Many amps struggle with this because they are reaching the current limit. In a perfect world, as you reach 0 impedance, you should get near infinite current. Then, Earth can have unlimited power. :D
However, due to real world limitations of the components used, many amps drop the voltage as the impedance load drops. The power delivery system, as well as all that is linked to it, can only manage so much before it is overloaded and fried. I remember reading an example on headfi: imagine you hook a cheap amp into a car's subwoofer array. You will blow a fuse because the amplifier is going to be pushed way past it's max output.
That is my understanding. I hope I explained it out well and did not misunderstand anything again. Feel free to correct me if I said anything wrong!
Cheers. : )

U-3CAhhh got it cheers; electrostatic headphones are good in concept but we are not at a level where portable amps can drive them reliably and efficiently. Best to go for the grado sr325e or sennheiser hd600 then.
