Presswerk is a great dynamics solution for your DAW. It just sounds nice and musical and it can do basically anything. but like most U-He plugins its a monster CPU hit so beware. This is right in there with the new Arouser plugin for great dynamics software. This guy is not for the unitiated, you can really fuck your sounds up with this if you don't know how compression works. its also quite expensive, I got it at a cheap introductory rate but I think I would pony up for it. I think you can try a demo version so you should check it out. If you're new to compression try sticking with the simplified modes that do LA2A, 1176 and Fairchild style compression respectively. They sound different than say the Waves emulations but are nice.
I think where Presswerk stands out for me is in M/S mode.... I tend to go for this guy when I wanna fuck with the stereo image but not with an m/s EQ or a generic width plugins like waves S1 or A1 stereo control or whatever. You can do some really interesting stuff with this carrying the dynamics between the middle and sides of a group or even your stereo mix bus. This also ahs a superb sidechain, even just using the fitlers its nice and the listen feature really puts it over.
This is an EXCELLENT analog-ish compressor plugin. If you can only have 2 compressors its this and Arouser.
