I get the principle but you are actually adding two issues for live mixing. One is that you have a parametric EQ sitting there waiting to be engaged that can handle all the punchy and brighter. You also have a second EQ already engaged right there inserted into the L and R which is now fighting with the expander. Were you to just engage the parametric by selecting the mains and turning it on, do your brightening there, and leave the graphic set to zero strictly to narrow out problematic frequencies you could achieve all of this. Go back to the main bus and engage the compressor and you have the mastering sound to play with. If you add a stereo enhancer into this LIVE you are merely going to throw things out of phase and start cancelling things all over. You have a built in speaker delay in the main menu already if that is what you want in terms of a stereo spread.... You have to remember that everything in a digital console is based around compression. No matter what it is, it is recompressing the DATA, the actual 48K or 44.1 Khz data stream. Adding more and more inserts is defeating that purpose as well.
