Nearly all multi stage amps need a capacitor in line to facilitate the bridge between the two. The trouble is, any capacitor or resistor in line with the signal is going to add it's own degradation of the signal.
It isn't easy to create a circuit with no resistors or capacitors in line with the signal. The Pass X and XA series not only do without, any bit of distortion getting through is canceled at the output through Supersymmetry.
