@goodlistening64 yes I am on a dedicated line for over 20 years in this house. Also have whole house surge suppression. Never once has it triggered. I am also on the same grid as emergency services in our town, have only ever had 2 outages in 20 years both due to a line cut.
Surgue suppression is not the same as conditioner that alters the current and can throttle hi draw equipment such as power amplifiers, and or integrated amplifiers.
