Tried the high level inputs - Nothing
Tried rsetting microproccesor on the denon - Nothing
Tried an old AVR with high level input (No SW output) - Nothing
I'm going to replace all the fuses in the sub amps tomorrow even though they tested good with an ohm meter. If that doesn't work I'll make the call to axiom. As far as I can tell it seems to be a sub amp problem seem to have ruled out the AVR.

On a positive note the M 80's put out some huge bass for their size. just not quite as much as the 600's, still sounds awesome though.
