Which includes ours, which also do not have a ZOBEL network at their output.
Usually that network is there to stabilize an amplifier at high frequencies- in particular, ultrasonic. You're more likely to see such a network if the amplifier employs feedback. It really won't have much to do with whether a coupling cap is used by the amp or not. At any rate a ZOBEL network won't hinder things.
