I really love the protection on these ADA amps. Before they can distort or worse (ignite or pop a component), the channel in distress gracefully temporarily shuts down. When I say temporarily, I mean transiently. It's not like it turns off and takes minutes or even seconds to come back again. Sometimes the protection is silent, and sometimes I can hear a slight pop. I suppose there's a turn-off transient somewhere that arises in the circuit. That's not a big deal; it's just an observation.
