Chang Lightspeed is the brainchild of Michael Chang, who wanted to design the best powerline filters on the market. Chang Lightspeed claims their filters eliminate AC contamination without the use lag or noise inducing transformers or coils. Located in Sylvania, Ohio, Chang Lightspeed has been manufacturing powerline filters since the summer of 1991. Each filter is hand assembled and fully tested before it gets shipped out.
