Jumpers - How good do they really have to be?

Consider that your question considers the effect of using a couple of inches of wire between your speaker cable and the internal wiring (which for sure is not the same). Personally, I would opt for the less expensive version of AP's jumpers as I suspect you would never hear a difference between them and the more expensive ones. FWIW.

The best jumpers will be your calbes.
Totem Manis have excellent WBT connectors that do not require any termination of the wire.
I use AP12 and thread the wires through the binding posts.

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.
