I know that Mastering.com recommends ARC for room correction for monitors, but what is recommended for calibrating / correcting headphones?? Do y'all still use SonarWorks for that, because ARC doesn't contain headphone calibration. Mastering.com leaders, please advise. Btw, I'm using a pair of Audeze MM500 headphones and I had heard that calibration of headphones takes it to the next level.
