I recenyly added a rel sub to my system and used their suppied cable. Problem is if I turn off my amp I get a very loud 60 cycle hum from the rel. It seems to me something is not grounded correctly? Can anyone help?
try having all your cords coming from the same outlet. then try cheater plugs on each component, swap around till it hopefully goes away.or call sumiko for advice, very nice and sharp guys in their tech dept.
