It's a plain cascode, increasing the speed, lowering the distortion. That's the piece I know. What I don't know is the advantage of biasing the cascodes base with a high impedance via a CCS. Rüdiger

You want the voltage to be floating between the emitters of the input transistors and the emitters of the upper cascode transistors. A big cap + a high resistor value forms a floating voltage.
