I can't tell you anything about the Kontakt libraries, since I use Dimension Pro (I'm ghetto
I hear good things about the ZR-76. I found a Youtube video demoing it here:
I am really not sure how well the Ensoniq holds up today, especially considering the Proteus 2000 is also a general purpose soundset and is more popular.
The EMAX and Vintage Pro will probably sound too dated for you, and might be redundant because you already own the M1? Someone correct me there if I'm wrong.
I would strongly urge you in the direction of the Proteus 2000. I would recommend picking up the Proteus 2000 soundset for general purpose sounds, as it'll probably sound a bit more modern compared to the ZR-76 (just my limited opinion here). The Proteus can do a lot of different things and is the quintessential rompler soundset (but it has no french horns!) You can get the ZR-76 on its own, if you really want it, but it may not be worth it. Buying a second and third expansion depending on what you want to do might be better?
The Virtuoso 2000 is the orchestral set.
Planet Earth contains all the world sounds.
The Xtreme Lead is the synthpop/electronica set.
Mo Phatt is the hip hop set.
Edit: Actually, the ZR-76 might fill in all the gaps of the Proteus 2000, and therefore might be worth getting? It does seem to have sounds the Proteus 2000 doesn't. But I'm not really sure about how good it is. I can't say.
Edit #2: The more I learn about/hear of the ZR-76, the more I like it and think you should get it.
It sounds old to me, though. I'm not entirely sold on it based on that demo I sent you, which was evidently a demo song? So I can only imagine how good those sounds can be when you learn how to use them.
This thread has a lot of good information by Planeshifter, who actually owns the real thing: http://www.kvraudio.com/forum/viewtopic.php?t=330924
So in the end, I guess I would go ZR76 and/or Proteus 2000 and whatever else you need.
I only am kind of advocating the ZR76 because it seems to have stronger orchestral sounds. The Proteus 2000 has orchestral sounds in it, but not a lot of them, and it definitely can't get the orchestral mock-ups the ZR-76 apparently can.
