Obviously you are not disproving anything. The "current split" is negligible (things moving at speed of light, remember?) And when  I say negligible it means way beyond the capability of measurement instruments detection, let alone the human hearing.

So then what's your explanation as to why I'm hearing differences?  Placebo?  I really wish you could come over to hear this, because the difference is not small...I've done other tweaks where I have to really listen hard to hear the changes and wonder whether or not I'm really hearing them.  But not this one...this one, the difference is pretty startling.  In one of my systems, I'm actually finding it not to my liking...

What about bad electrical contact? Contacts were a bit loosen/oxidized. When you switched the newly tied up screws brushed a little bit of oxidation away. I don't see any other logical explanation.

Has anyone tried this variation, where you tie the negative posts together with a jumper in a traditional biwire (two pr cables both connected to the amp) setup?
I haven't tried this in ages, but hey it's free and some claim a difference.

The way I see it, my jumpers are of a different gauge/design than my speaker cables (speaker cables are 8awg, jumpers are 10awg) .  When changing which terminal the speaker cables are connected to, I'm essentially changing the gauge/design of the cable feeding the high/low terminals...and the gauge of the cables affects the current flow into the terminals.  I think that makes a lot more logical sense than "brushing a little bit of oxidation away"....

I did this with Zybar an hour or so before the August NY Audio Rave started.  I had my speakers bi-wired with two runs of the same cable.  Zybar thought the overall sound was a little diffuse and the bass was too soft.  So I put a jumper on the negative post, and the bass tightened up a little bit.  Then I removed the bi-wire completely and added jumpers from the low to the highs, and everything focused much better...so we left the setup single-wired with jumpers...

It would be great to be so emphatic if it were only true. Biwiring in my system, using a low output impedance amp and cable pairs with drastic gauge differences, it is easy to hear the output balance favoring the path with the much thicker cable attached (lower resistance path). Swap the cable pairs and the balance shifts.

Actually having tried this, I will take Phil's experience with his system over half-informed dogma any day.

On a whim after talking with a couple of audiophile friends, I tried changing my jumper setup on my speakers.  Originally, I ran my speaker cables to the low-frequency terminals on my speakers, then jumped from the low terminals to the high terminals.  I just changed it so that the speaker cables run to the high terminals, then jump down to the low terminals. 

Whoa...! 

I wasn't expecting to hear much difference, but the results are stunning quite frankly.  Soundstage has opened up, detail has increased by more than I thought possible...I am 99% sure I am not imagining the differences. 

Anyone else have an ability to try this?  I've done it to two of my systems, and in both cases the changes were not small...

Yes, that difference may be in better midrange or top air but the bass gets slower and less articulation.  aa

I have removed the gold plated steel jumpers between the lo and hi inputs on my Paradigm Studio 40v.3's and replaced the jumpers with speaker wire. I then put the bananas into the lo input terminals. Now I have bass whereas before, the speakers were too bright for my tastes.

As far as Ohm's law, I just put my Ohm meter test leads on the jumper bracket and found a .6 ohm resistance through the strap. That is a lot!

Steel isn't a real good conductor and neither is gold. Silver is best, then copper and aluminum.

Speaker manufacturers should be reconsidering supplying the cheap terminal jumpers as I do believe it is an issue. Not everyone is bi-amping or bi-wiring.
