You sound like a politician. Talking without speaking
My question was not about what I'd want from it, if I'd like it or what alternatives there are (btw, the II's enhancer works very different).
It's just that, from what I know (the experts may correct me), that comb filtering occurs
just then when you mix a signal with a delayed version of itself. If you keep the signals separate, you don't get filtering as such (like notches in the freq. band) but a perceived stereo widening ("Haas effect").
And my question was: do the big artits you're referring to use it à la version 1 (mixing signals) or à la version 2 (signals separate)?
If you don't know, then just say so
