I downloaded the Flux Alchemist demo version in the meantime and tweaked the parameters a little bit. All I can say is: Mindblowing!!!
You have so many parameters to tweak, but the potential of this Plugin is quite awesome. I especially liked the M/S processing feature for every single band (quite useful for bass frequencies in my opinion). The possibility to change stereo spread for each band is also quite handy, as you can just widen a little frequency range without messing up your bass. All in all I can say it's a really great software, but you have to learn how to set it up correctly. You can have lots of fun with this Plugin, but it really needs to be learned in my opinion.
