Last night while moving my amp (yet again) I forgot to turn off the main power on the amp (stupid me) and when I disconnected the interconnects from the preamp, I might have touched two interconnects and I heard a loud crackling noise from one of the surround channel speakers. I immediately turned the amp power off. But my question is could I have done any harm to the amp by contacting two of the interconnects (still attached to the amp). I still haven't hooked the amp back together but would like to get some expert opinions on this issues. Thanks in advance.
