1 sets of Mapleshade Audio Clearview Biwire Jumpers for sale. These are the ones with silver leads soldered directly to the copper ribbon. New these are $75 for a set of four. I am offering an unopened set for $24. The key thing to understand about these is:​

"The usual jumpers that come with bi-wirable speakers cause a most unfortunate degradation in sound quality. (Incidentally, half the improvement that people hear when bi-wiring is due to getting rid of these poor-sounding jumpers.) To replace these jumpers, we offer, at low cost, a set of very thin copper ribbon jumpers. This ribbon is identical to the conductors used in our state-of-the-art $1600 Omega Mikro speaker cables. The difference you hear is a startling tribute to how much sonic improvement can be gained from only three inches of first-rate conductor."

Price includes shipping and fees. Cheers and thanks for looking.
