Thanks for the help. I did get a set of these jumpers with my cables, but I didn't put them on initially because the Goertz literature said to use them if necessary. I haven't had any problems without them, but I went ahead and installed them this evening just to be safe. I was afraid they would effect the sound, but it doesn't appear they do, so no big deal.
Glad this turns out to be a non issue, because I'm completely satisfied with the performance of this cable.
