using a jumper cable - connect which set of post?

I say hedge your bet by plugging your speaker wire into one up and one down post...and reverse them every other day. The distinction between biwire cables and jumpers is clear as it regards 2 wiring scenarios, but my main speakers (Silverline Preludes) sound better single wired with the supplied gold plated brass jumpers...more coherent, unlike myself. I was told by the speaker's designer that this was the case, and was also warned NOT to lose the jumpers as he would charge me for new ones. I assume he's replaced more than a few of these so he's not shy about the warning. I think wondering what posts to use for the main wire with jumpers is a classic example of the gonzo side of this hobby, along with claiming that the use of a one inch strip of your wire instead of a pair of thick solid brass jumpers would somehow make an audible difference...but then I like gonzo.

If the posts are connected by a jumper cable, they are electrically the same point. Therefore................

I can respect the point that it should make no difference at all. That is not what my ears are telling me though. Also, the fact that I am using the stock jumper cables that came with my speakers. I am not using a shortened piece of cable that is identical to my main cables. I have had my main cables connected to the low frequency post for over a year now. I am very familiar with that sound. When I did switch it to the high post, it did brighten the sound to a degree. I don't know if this is because of a loss of bass or a better connection to the mid/tweet. After listening to these speakers with the cables on the low post for such a long time, this sounded too bright to me. Nothing has changed drastically but, I can detect a subtle change. The thought never crossed my mind to connect one wire to the high post and one to the low. I did try this and I like it better than connecting both to the high post only. It seems a bit more detailed and not as bright in the high post connection. I will say again, this is not a night and day difference. It is subtle but, it does exist. I have had other people in the room listen and not tell them what post I have switched it to. It can be picked up by other people as well. I think I will leave it in this high/low connection for a bit and see how I like it.

See? I rest my case. I love this stuff.

My experience,and the experience of the two guys who listened with me, was that there was a readily detectable difference between using the top and bottom -- more readily detectable than a lot of other differences routinely claimed to be "not subtle."

It may be that the differences was just "different" not "better" or "worse" -- matter of personal taste -- but my speakers seem to do better in the low using the low posts.
