Amps are often tested using inductive circuits, which limit the inrush current. The inrush current can actually be larger when they are plugged into a low-inductance high-voltage dedicated circuits. B&K's have been known to do this. They blow fuses a lot. It is nothing to be concerned about. You should probably put the amp on a 20-amp circuit. You probably have dedicated wiring for this don't you? Another solution is to put inrush limiters or a relay and a power resistor in the amp. This is more typical of high-power amps.
