Do Jumpers make an audible difference?

My speakers are Joseph Audio Pulsars. The Nordost work fine however like many in this hobby I'm always looking for areas to improve. Thanks to all.

I had the same exsperience as Zavato, when I took the Bi-amp stock plates off, and installed Tara labs Omega Jumpers, that are 10 inches,They only cost $800.00 and come with bananas and spades, these Jumpers are the most profound jump in performance I have EVER put on my system, It is my opinion, that not all jumpers can achieve this performance level, and I believe that 10 inches, being shorter, that running another pair of speaker cables cannot result the same resolution because the signal looses intergrity by having to travel a longer distance, Enjoy the music.

I should think cryoing the jumpers and installing them in the correct direction would be as good idea. Ditto the fuses.

What I wonder is how many of those who have experienced significant sonic improvements by upgrading jumpers have gone back and forth two or three or more times between the original and upgraded jumpers, to verify that the improvement was not simply due to differences in contact pressure, or to extraneous variables such as equipment being in unequal states of warmup. And if prior to performing the comparison a good contact cleaner was used to assure that oxidation on the surfaces of the original jumpers was not a factor.

There will be no resolution lost in a second pair of, let's say 2M, speaker cables.

Just wanted to correct a previous post.
