I've used the Precision Limiter for years as a somewhat transparent end of chain limiter on the master bus. After closely comparing it with the C-Max on a recent project, I'm replacing the P-Lim in the chain with this plugin. This is much more transparent. As long as the "aggression" setting is at 0, I can't hear a difference in the original source until it's pushed to very squashed levels. Not sure what some of the reviewers are hearing in saying it is colored. It isn't.
Only taking away one star because of the hefty price and the need for better "sticky" metering that holds the max reduction amount.
