BTW, as a 'mastering' rookie I thought the mastering presets in logic sounded pretty sweet (and they do). Clearly though, I find the presets in Ozone to be just a bit better. Higher highs, clear penetrating lows, great 'loudness boost' etc. More presets too and over a larger variety of styles than Logic. Of course I'm only speaking of presets which, for the time being, a guy like me needs. Also, Ozone gives very good 'mastering tutoring' documentation with the product. I'm sure the 'mastering lessons' included with Ozone will only help with my understanding of Logic's mastering suite. I would highly recommend Ozone to any Logic users. For $249 not a huge buck. ~KIng
