Michael Chang, engineer and stereophile, designed the Lightspeed Powerline Filters after being disappointed with the powerline filters available on the market. Mr. Chang's design eliminates AC contamination without the use of lag/noise inducing transformers or coils. In 1991, Michael and his sister Stella founded Chang Audio Corporation.


A small staff of technicians hand assembles and tests each unit from quality parts before it is shipped out. The combination of this care in craftsmanship, with the effectiveness of filtration and the units' low cost, has won Chang Lightspeed Powerline Filters acclaim and buyers worldwide.
