Hard to say Ken, but I know Axiom tests them before they ship. I've had to replace a new Panny Plasma right out of the box that would not turn on, Emotiva top of the line MPS-1 monoblock amps right out of the box that kept shutting down, and an Axiom EP500 amp (wasn't Axiom's fault, Fed Ex ran over it with a fork lift). This happens to all manufacturers; subs, amps, speakers, you name it.
