Crap. Now I have to go rewire all of my stuff.
Terminating everything on 110 or 66 blocks is the way to go. No more stripping wires or using wire nuts for stuff, just punch the wires down and let the punchdown tool cut off the remainder.

Using the bus techniques makes it really easy to layout the wiring for your ELK speakers and get the right resistance on everything.
