Easy mistake to make. Like Douglas says don’t make a habit out of it. Unlikely to have damaged anything if all sounds good. They can take more than you think.
Any way I could have damaged my speakers?
Yeah, so I was changing out some interconnects on my preamp while it and the amp was on. I temporarily pulled out the rca cables that connect to the amp from my preamp and heard a screech from the speakers. Playing some music now and sounds fine but I'm obsessive compulsive. Any possibility I damaged anything?
