I have run ARC twice with 2 different MRX-1120 receivers and the results were nearly identical. It found peaks and nulls in virtually the same spots and frequencies, and the corrected curves are pretty much spot on target. Plus it just sounds good and pretty much identical. There were times running Audyessey where I would run it once, not like the resulting sound, and run it again and get something better. All using the same (or as close as humanly possible) mic positions.
