What is the input impedance of these - is it 600 ohms??
I am wondering because I really like the sound of the 600 ohm 240DF (diffuse field) model, and if these are the same as the DFs, I might be interested.
For others attracted by my enthusiasm, the 600 ohm models are pigs to drive and absolutely require a serious amp to get any kind of level out of them.
So, what I'm saying is that you wouldn't want them! aa
