Ahh, but do you also get him to drive it with some soothing pink noise to loosen up those driver suspensions, say ... :b:bWarm-up time!
My amp starts sounding decent after 15 minutes, but ready until 40-45 minutes where bass gets rounder, fuller and soundstage goes 1mt behind the speakers. I need to call my son some days to turn it on while driving back home....
