Charles, I've pondered this for a few minutes and I certainly can't think of anything that you've missed. You checked the 1000-4 with two different voltage sources and got no response. Does the 1000-4 have some sort of power-on light? Contact Axiom, of course, to see if there's something weird about operating it that we're not aware of.

Sure, until you get the new amp problem fixed you can use the Emotiva for just the front drivers, but I'm still of the view that you should try the receiver again as we discussed before to get full operation of the LFR1100s.

Enjoy the music, not the equipment.
