Well, I downloaded the plugin (they want names and emails, so I hope I don't get spammed)
First impressions are that it does brighten the top end a bit (although it can get a bit squishy if the effect is turned up too far), and the tru bass is quite good at enhancing the sound...
Certainly switching back to normal sounds flat and uninteresting...

However, it does produce 'artifacts', and I suspect you could do quite well with just an eq...
So, I might use it on my home system (on almost min settings) but it's odd, it doesn't improve sound quality, just makes it 'nicer' to listen to... =)

That probably doesn't make much sense... If anyone's interested I could record a before and after sample via my sblive?
