kr4, not sure you understand what I'm asking and I don't understand your response. Use the same wires as jumpers instead of jumpers...?What Kal (KR4) is suggesting is using jumpers that consist of the same kind of wire that is used for the speaker's internal connections to the binding posts.
Assuming that the required jumper length is short, and given that most and probably all predictable speaker cable effects can be expected to be proportional to length, that sounds like a good approach to me.
