"The only adverse effect on the operation of a McIntosh amplifier when it is improperly matched is reduction in the amount of distortion-free power available to the loudspeaker. Close impedance matching is desirable for maximum distortion-free power."
"The amplifier is completely stable when connected to any loudspeaker system or even to any reactive loads. The MC50 has special circuits to prevent damage by any short circuit or open circuit of the output load, or by any amount of output impedance mismatch."

It's sorta a 'square-wave' clipping sound. I've ruled out the speakers and anything else; I suspect I'm clipping the sentry. I'm not sure what really to do other than disengage the sentry (which I have no idea how to do). I hope I'm not hurting anything by continuing to play with it like this... Am I?
