thanks, shall try a ring and some clip ons, also wonder if this is a cheap solution to someone wanting to reduce the noise from their standard SBT PS. Am using a powerful ring magnet with 9 turns for my laptop supply at the moment, post switcher), but feel the ferrites will be safer. -- SBGK ------------------------------------------------------------------------ SBGK's Profile: http://forums.slimdevices.com/member.php?userid=52003 View this thread: http://forums.slimdevices.com/showthread.php?t=91322 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
