I used the “Perfect” equalizer settings, shared by Merlin Mann, when I first saw it on his site many years ago. But I mostly abandoned equalizer settings when my music playback transitioned to mobile.
I was poking around Prism yesterday, though, and remembered it had an equalizer setting that I’ve never used. For whatever reason, these old iTunes settings sprung to mind, I did a bit of searching to find them, and I plan to give them a try in Prism. The app’s settings don’t quite line up perfectly with iTunes, so it’ll take a bit of tuning to get right.
