Ok, thats great. So since thats the case, it should run those Athena's effortlesly, so I would bring it back to BB, and have them do an even exchange. A second unit is 99.9% chance of not being faulty. Or at least not the same fault. If by chance at that time you still have the same problem, I would open up all of those Athena's to make sure there is no direct short inside them....
