My Jumpers are made from the same wire and process as my Cryo Nova cables.

Solid core OFC 99.9999 pure copper

If you are using stock jumpers on your speakers, you are losing detail and clarity. Stock jumpers are the worst connection you can have between your speaker's binding post. If your using my speaker cables and aren't using my jumpers, you're not getting 100% of the benefits of my cables.

If you're using another manufacturers cables and want to get the most out of them, put my jumpers in and you'll be amazed.
