I've been testing this new release till now as soon as I got the demo and wrote positive comments here before.There's enough info on site+manual so I'm not going to get into detail but if you want to try for yourself;

You can first listen audio demo's and later if you like, download Nebula free and then the demo library from the site (there is no time limit for any of them). Till now I tested only for mastering (mostly electronica and also rock genre) needs but enough audio demo's are provided to get the picture.
Demo: Same quality with commercial but limited bias and drive amounts.
What I liked was boosting the controls+balancing levels and noticed a very special glue thats not similar to anything I tried itb before.
When inserted, I noticed tracks didn't need as much eq'ing and when loudness is required it worked great right before a compressor sort of plug-in (compressor, limiter or even clipper). To get more of that magic, more instances can be inserted but always leave some headroom.
Commercial: With commercial version you get a second color preset and demo preset controls go up to 9 db.
More control brings more possibility's. Maybe some have read Bob Katz's book and remember the compressor+expander trick, similar effect (yes, with VCult coloration!) can be achieved with the right settings but its not limited to that.
On my tests I noticed it can bring back or add dynamics in a very fast but still musical way, it can bring focus/save vocals that's level is lower than ideal (and that's something not easy to do with other tools), bring back punch either in micro dynamic or section beginnings of songs, widen very good when inserted to S (like in m/s), add some musical gain, glue alone or with compressor (insert compressor after it)...Really, its a Swiss army knife that only needs adjustment total of 5 sliders (3 with P6 preset, including in-out gain sliders).
I highly recommend it for people who master their own tracks since it brings nice balance and minimizes the need of eq, actually I got very good results together with freeware like Melda plug-ins or SonEQ.
The developer also has a product called "so transcited" at his website. From what I hear when using, (though un-sure) it helps correcting the fletcher-munson effect which usually is responsible for mixes not to translate to the real world. That also has a demo with limited settings but keep in mind adding a deesser (the freeware spitfish usually works fine) after it or high-cut with eq might be needed. Together with VCult, they work nice together.
Using it with vsti's or recordings is a different story, listen the audio files to have a clue
