Caleb, I am using a Yamaha RXV-2500. I do hate the automatic sound set up on it the YPAO is a piece of junk, but manual works fine and the reciever is solid and the Aperions sound great with it.
Funny story to tell you when I was hooking up my speakers I hooked up the center first and my partner ran into the family room and said he could hear the improvement. I laughed when I told him this was just the center and had not even hooked up the fronts or rear yet. Still am working on the SPL meter and not sure if I am using it correctly but the arrow seems to line up even on all the speakers so I guess that is right but it does sound balanced to my ears and that is all that matter.
