For the price of the Belkin, consider at least one dedicated line [3 is better] and perhaps a whole house suppressor at the panel. Few standalone AC units do anything good for most amps, esp. high power, high draw amps such as yours. A few tout "zero insertion loss" but claims and reality often diverge widely/wildly here.
That said, I've had good experience with the AudoiPrism units which actually seem to substantiate their claims. My units also cost less than some power cords, and the build quality is second to none. You might also consider the Blue Circle units and those from Audio Magic.
