OK guys, sorry i wasn't around yesterday, did not have time to do any other tests. Just a note, the speakers will play at lower volumes, only when you turn it up dose the amp shut down.( so i "ASSUME") the M80's just drop too low, ohm wise then this amp wants to see.

I will go thru all the connections again..double check everything. The first thing i will do is connect the old large Advents up, and run them at volume. Just to make sure i didn't damage the amp.
By the way, dose anybody run QSC, or Crown amps to power the M80?
Altho not really considered "Stereophile" amps, they do put out the power and can drop to 2 ohm's without a problem. I could get one of those shipped to the house in a few days. If one of those amps shuts down...then it's for sure a problem with the speakers. Those amps i can just send back, no questions asked.
