This plug is killer. On properly mixed material it can raise the overall level to commercial states. It can be overdone but it is hard to do with proper source material. Literature states it can bring a -6 reduction without noticeable pumping. I never had reduction numbers like that but I did pull about minus 2-3 with a substantial boost in the overall volume without hearing any clamping down. The source material is the key to using the plug, if your material is compressed and processed heavily already you will not get a transparent limiting and boost. But on the other hand if it is a raw mix and not overly compressed it will set the mix up front loud and proud. I held out for the longest time on Waves plugs because they used to require the ilok authorization, but with version 9 on most plugs it is no longer needed (big plus Waves). If you need a plug in to get your mix up to commercial levels, this is it.
