Has anybody tried covering unused rca jacks on their preamp or a/v receiver with Cardas Caps? Another snake oil remedy or sonically worthwhile? Thanks, Ed
Mine lowered the volume of a slight buzz in my system, but didn't completely get rid of it. It does buy peace of mind however, knowing that a hum is not due to open rca jacks is helpful.
Installed the caps in my LS7 and did not notice a difference. The above statements are true however as to system dependency. The caps are well made and provide a tight fit.
