Hi, I know this thread is old but I hope someone can answer my question. I have three Crown itech amps which are 20 amp. I have been using a Furman 20amp to 15amp adapter since I do not have 20amp receptacles in my home, and thus far I have never had any issues or tripped my breaker. I am shopping for a BrickWall or ZeroSurge protector and trying to decide what the better route would be. Purchasing a 20 am surge and using a single Furman adapter to connect to the wall or purchasing a 15amp surge protector and using the adapters with my amps which I am currently doing? Pros and cons? Which is optimal for performance and protection?
