BBE is nice. I have two plugins which I use all the time for enhancment: the "Spectralizer" from Steinberg and the Waves "Stereo Imager". The Spectralizer has a very nice 'kick' switch which is ideal for lifiting a percussion instrument out of a mix. Spectralizer makes enhancment that doesn't sound like it has been treated artificially. You can however, 'abuse' it's settings and get the sound of one of those high frequency 'stimulators', but with no added noise. a GREAT plugin imo.
The Stereo Imager allows control of the overall stereo width, a really important function particularily for orchestral music. The OZONE plugin is good too for modifiying the stereo width of individual bands, but the 'exciter' portion sounds too juiced for orchestral music.
I used to own a hardware box of the BBE and several other 'enhancers' but then I learned to make better mixes in the first place so I didn't need much of any enhancment. With the PC now, I find the old enhancements work well when brought forward into the digital age via plugin technology..
I don't own it, but I've listened to its after effects... I'll say its a very nice program. Has it been updated recently. It's been out a while now. I lost touch with the whole plug in scene. My budget only allows for 'free ware' stuff so I stopped dreaming about these type of expensive plugins.
