Onkyo calls their loudness compensation/equal loudness contour/Fletcher-Munson curve the "Music Optimizer". It supposedly restores compressed music, but to my ears, it's just a loudness switch. I use it when I listen to music at level 45 or less. It doesn't appear to do anything to compressed music, unlike the magical Sony DSEE HX engine in some of their headphone products.
