Lightspeed

Michael Chang, engineer and stereophile, designed the Lightspeed Powerline Filters after being disappointed with the powerline filters available on the market. Michael'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.
