Nice system!
Saw in a nother post your dedicated lines bypass wall outlets and power cords, and the gear ends are terminated with upgraded IECs. I'm about to install dedicated lines myself and have contemplated this very method to: a) save money; b) obtain the best IEC connectors I can afford with the money saved on eschewing outlets, covers, and power cords; c) least connectors -> optimal electical path.
1. Did you also verify or replace the IEC connectors in your gear as well?
2. Have you done anything special at the power panel?
