So I have had this problem with these Jamo bookshelf speakers before. I got them from a friend's parent, they upgraded their speakers so I received them in a functioning condition. However, whenever I have tried to connect them to my Denon receiver, there is a lot of static and very faint signal coming from either my record player or TV. I know this is not an issue with the receiver as I have had success with other speakers. I refuse to believe these speakers do not work, and would love any help anyone could give. The only thing I can think of is in their previous setup they had very very thick speaker wire.
