I'm wiring up (or getting ready to) a 2 box Dynahi build and a new Buffalo III pro build. If I read the Rane article, the Tortuga article, and this post correctly I should connect IEC inlet ground to the chassis, Pin 1 of each XLR to the chassis, and PSU ground to the chassis for each box, then float the pot grounds in the Dynahi amp box. Is that correct?
