I'm a fan! If you are bouncing stems that you want to all add up to that sound though, its best used as a guide and try and emulate the sound back in the mix.I've got Ozone 9 advanced as an upgrade.However, I find myself going back to the presets in Abbey Road TG Mastering Chain.It's a cpu hog but surprised me how it gave instant quick solutions for a variety of different tracks- on sale as Waves plug-ins frequently are!
Easier said than done! It's a great sounding plugin.
