Hey guys, i just got a marantz 5006 which im impressed by so far. however, when im playing music off my ipod with the volume pretty high, the lights in the room dim with the base notes. my basement is all on one 15amp breaker. has anyone else had any issues like this? do i need to run an additional circuit to the receiver or do you think there could be an issue with my wiring in the house? thanks.
