Baxter is imo the best free deal on the internet.
The whole Coral2 plugin, once you really start using it, for modern but analog sound, its insane value.
Preamp AIR is great for strings, instant pro sound, tape preamp is great as a bus preamp, makes it more analog less harsh.
I have seen people selling it, not understanding what a powerful suit of plugins this really is.
The BAX eq, the stereo version can totally replace Diamond 3 for the mids and highs even lows, while not as punchy as Diamond is punchy in its own way.
This plugin is a sweet mastering suit that can give you pro results with ease.
