Not countless speakers as Adcoms in general are reliable amps. Also when an amp fails it does not always do so in a way that would take the speakers with it but in those few times that it does its adding injury to insult. You could give yourself some level of protection by putting fuses on one leg of the speaker wires. It is easy enough to figure out the fuse value. There are many who would argue that it will effect sound quality by doing so but then there are well respected amps in the market that have fuses or relays inline to the speakers for protection.
