Not wishing to express a view on the original posters identity here ... as that seems to have started a lively discussion ... but I would say that CLA has done a very nice job on the new Audio Legends course http://www.audiolegends.com/. I figure that's a $100 I spent on something much better than a few extra plugins. Its very helpful to turn stuff on and off (on the mastering chain) and see how all the subtle (and not-so-subtle, EQ) settings combine into a mix. Hint: turn OFF the FG-X at the end of the chain, as the mix is much better that way. The difference was rather a surprise, as I often lean on the master buss compression and limiter, probably more than I should it seems!
