Speaker jumper cables--a type of sound?

The classic issues that can make a difference in cables are related to factors such as length, wire diameter, configuration and so on; these affect resistance, capacitance, inductance and can also make the cable sensitive to external EMI influences.

Jumpers, by definition, are very short and therefore tend to contribute little toward adverse effects in the above mentioned areas.

I have certainly read accounts here and there of people who prefer one type of jumper over another, but even then I would expect any change to be less dramatic than what one experiences with longer cables.

As always, the thing to do is experiment for yourself and then run with what makes sense to you.

It makes more difference than you would think. I would go with ones from the same company as the main cables, not necessarily the same size. I have Cardas GRs and their jumper is much smaller but still works well.

Agree with Stanwal.

I used Analysis Plus jumpers as well as the same speaker cable.
