I was wondering what metal the dual binding posts and jumper plates were made of on my HT2-TLs. Plating? From what I can see the jumpers plates are Cardas but not sure about the posts. I saw a post on the Steve Hoffman forum that said most binding posts were made of brass. I was just curious if that was true or if copper was used more than brass. Still loving my HT2-TLs and all my Salk speakers!
