It has been a while since I have been back to report on my 770 issues. I have gone over the speaker connections, ran new wires across the floor, used different power sources, measured resistances, voltages, etc., etc., while operating the 770.

We have played a few movies now and the 770 works great for that. Without a constant loud volume, it works great.

I have accepted the fact that this amplifier does not dissipate enough heat to play music at the levels that I have been testing it at without a thermal shut down occurring. I will continue to do some testing as advised by you guys that are offering your help.

I have had a few conversations with the Outlaws and they have been supportive.
But the ball is in my court as they have offered to check it if I want to send it back. I am in Canada & with all the shipping
& duty issues, I don't know if I will.

I suspect that if they do test it they may find it OK for what they are using as a test system. I would like to have someone test it with the same speakers, 2 runs of 14 gauge wire to each, with the same material & volume levels to compare apples to apples. The material I have been using (to stay consistent) is Metallica - Master of Puppets at -05 db.

Even though I have an open back rack, with 8" + clearance above the 770 and at normal room temperature, I am planning to run a vent from the rack to a bathroom fan somewhere in the ceiling, or have a duct to the cold air return installed. That may cure it.

Of course, my visits to my B&M store, who sold me my Paradigms as well as many other pieces of gear over the years and who wanted to sell me Anthem product, see my with my hat in my hand("We told you so"). Would the Anthem stuff thermally shut down? I don't know.
The 950/770 combo is impressive for movies, and I think that they certainly compare to the AVM 20 or the Anthem power amps, (forget the difference in price) after spending hours listening to them in the store.
