ok its listening experiance ya want,try having 32+ channels coming in at ya and somfings "booming" my hand natruly grabs the correct channel and backs off the gain/bass/phase reverse/ whatever,or speaker stack 2 is 8 ms behind stack 5,mmm lets add a bit more delay ,but its  already automaticly  been set by the equipment.  20+ years of mixing live sound and yet i cant detect when a cable from my cd player is around the wrong way?
