Anyone using "jumper" cables?

Yes use them when my BMW does not start.

Karmatogdral,
If you own bi-wire speakers you basically have 2 ways to wire them, bi-wire cables or single runs with jumper. Experimentation should dictate which way you go for best sound. Also, you might discuss this subject with the speaker manufacturer to see if they have suggestions or recommendations.
One thing for sure though, the manufacturer supplied jumper plates are generally NOT the way to go.

There are 3 ways ... don't forget 2 single runs. Depending on the SC, speakers ... 1 of the 3 ways will work best.

Currently I'm using 2 single runs and the improvements over jumpers and bi-wire SC are tremendous.

I use 2 single runs but in a way I consider it bi-wiring, just that the amp end pairs are not actually physically connected.

So I guess you could then say 4 ways to wire bi-wire speakers: single runs with jumpers, internal bi-wire, external bi-wire, multiple single runs (8 individual wires-4 per side).

I use JPS Aluminata Speaker jumpers. They seem to work well with my speaker cables. Make sure you try both connections with your speaker cables. My system sounded better with the speaker cables on the treble side and the jumpers going to the bass side. It seems to make a difference on my speakers.
