Jumpers - How good do they really have to be?

I can't speak to your particular combination, but can tell you that when I got my Avantgarde Duos, I first hooked them up with the factory supplied jumpers while awaiting delivery of some custom Cardas Golden Ref. jumpers. The speakers were, admittedly, still breaking in at that time. The Cardas jumpers arrived, along with the Cardas speaker cables and interconnects- all the same stuff. Wired the system with that, and after that settled down (cable was used, so break in was not an issue) system sounded better. Then, I thought I heard a hum in one channel, and to isolate that, I tried everything, including at one point, going back to the factory jumpers. At that point, with speakers more broken in, other cables settled, and me used to the sound of the system, changing the jumpers in and out from the factory to the custom jobs was not subtle.
Also, are you sure that the cables you seek are not available for audition and/or purchase used? I would work on that front if the sticking point is paying retail....

there are many feet of standard wire in your speaker, just get something like that.

If you can buy the second pair of wire used for the price of new jumpers buy them and be done with it. The jumpers do have to be as good as the wire you are using to sound the same but you will not have the benifit of the extra guage of wire that you would get with a second run. Many will disagree with me and in the end you will just have to find out for yourself.

If it's only 2" distance then the main difference would come from mechanical contacts. Connect your speaker cables to the tweeter ports and jumper down to the woofer. It makes a difference!

I would just try to keep it the same as my main cable.
