Dirty (Color) Compressors

[DCrown]

Waves V comp ( Neve emu) and PIE Kramer (Olympic Studios)have lots of character, also WAves DPR 402, the latter can sound pretty dirty.
Waves Omnisheps a great channel strip with three compressors and by using the saturation you can make them sound dirty.
IKM's distressor emu can sound dirty, too.
For me they are rarely the right choice, but whenever I chose them they are the only right choice.

Not much aliasing when its not pushed to extreme

Would you consider -18 dBFS extreme?
