Since the petition has been online for over a year, I have revived various "Save SACD petition" threads at hometheaterforum.com, avsforum.com, audiocircle.com, sa-cd.net, Polk Audio forum, stevehoffman.tv and audioasylum.com. In addition, new "Save SACD petition" threads have been started at audiokarma.org, head-fi.org, stereophile.com forum, the Singaporean audiophile website echoloft.com and Hong Kong-based audiophile website review33.com
