>>>Series surge reactor current limiter.....<<<

This is quoted from the product info on the web page, and if it is what it seems to be, it is not what you want to feed a power amp with, marketing notwithstanding.

In an application where relatively unrestricted peak currents are needed as in a power amplifier, you don't want anything except a circuit breaker in series with the AC line. House circuit breakers can pass peak currents above their current rating for a short period of time before the heat generated by the current causes the breaker to trip.

With low level devices which do not consume high currents, this limitation does not really matter.
