It's well worth a trip down to his site for a set of other plugins that mostly seem to be about stereo manipulation - a multiband stereo enhancer, a bass mono-iser, high frequency generator and all kinds of other stuff that I'm not entirely sure what they do (it's in German, but mostly you can suss them out).
Go get 'em at:

Looks like some different-from the-norm plugins that are difficult to source usually. I'm definitely going to keep an eye on this feller....and thanks Matthias for making them free
