Voxengo Deft Compressor
When Aleksey says the product will 'do this and that thing' to the source material, it's easy to trust those words.
As it says on the overview of Deft Compressor:
"The characteristic feature of this compressor is its ability to produce “slim” and “slick” sounding compression, with intelligibility enhancement effect."
That is exactly what you're gonna get with this. It's amazingly transparent in the way it handles audio. My first time properly using it with a vocal, it didn't audibly squash the loud parts. It just gives you the character of the source you give it, but more even, and more slim and slick, and more intelligible. I know that's what the product overview said, but I have no better way to describe what it does.
Crunchessor - good for drums and percussions. Fixed ratio, “style” selector - suitable for adjusting the sound for any genre and character.
Deft compressor - good for other track types. Punch knob - excellent for transients/attack management
Marquis compressor - good as SSL analog for gluing groups (variable soft mode of amplifier - pleasant to the ear).
I recommend all three compressors at once for purchase.
