I've actually been using it on almost every mix I've done over the past year or so on background vocals, usually getting around 4-5db of gain reduction happening on the LED's, and using the makeup gain to taste. At the studio I'm doing my mixing at these days, there's a ton of awesome sounding and esoteric compressors, but honestly, there's nothing really that sounds better than the RNC for this application. I don't use it for anything else, though.
