 @John Warren has a PhD in Materials Science Engineering and worked in aerospace where this stuff really matters, i.e. thermal conductivity of internal parts in turboprop and jet engines that we fly around in. He might have some thoughts. 

 

Oh my! and yes, University of Virginia, 1994, PhD Materials Science and Engineering.

 

Unfortunately, products with the goofiest claims in audio are associated with materials science, more specifically, metallurgy. 

 

However, the absolute STUPIDEST thing in audio is a non-existent physical phenomenon that cable "lifts" are solving, the so-called interaction between the electrons passing thru the cable and the floor.  FFS, Maxwell would get a laugh out of that one!

@Travis In Austin, that "loop" comment was made with tongue in cheek. For such a tiny portion of the signal path, there isn't much short of replacing the jumper with a resistor (or a capacitor or an inductor) that will make any significant difference.

If there is any difference to one's ears I would think it is a change in capacitance or inductance. If any 2 inch jumper is purely resistive and you can hear a difference your auditory system needs to be studied by the top audiologists in the world.

I take everything you say as gospel, you will need to come up with a color/font to distinguish TIC 😃

I'm sorry, @Travis In Austin. I should have added a sarcasm emoji -- it is a severe limitation of written correspondence that "tone" is difficult to convey.

 

To summarize: Theory and mathematics can be misused to prove just about anything. For a little 2" section of wire connecting between an amplifier and a voice coil, one really cannot do anything that seriously affects the signal unless they are trying really hard to do so.

I confess that I did a test once with 3 sets of jumpers. OEM mystery metal bars (relatively expensive speaker), the jumpers above, and left over pieces of 12 awg mil spec silver plated copper unterminated.  No difference to my old ears. I was very tempted to leave the mil spec cable bits in place. Total cost comparison; maybe $0.50 for left over mil spec bits, vs $70 for the jumpers, vs sunk cost on the OEM mystery metal bars.  But you have to make the shiny jumpers, no?

That is the rational approach to me. In audio or speakers there are a 1,000 different things that can have a claim as an “improvement.” There are many who will read or hear that I switched my tweeters to this and “it wasn’t subtle” and always an improvement with adjectives (fuller, open, faster, etc.) - Berneak’s law, similar to IKEA effect (a real thing studied and subjected to peer review).

 

You said I’m going to check this out and see/hear for myself. I like it a lot.

To be honest, I can hear the difference in which type of cable, plug or other connection is used. Depending on the speaker, I can also clearly hear whether I plug the cables into the treble or bass input. When I made a few tweaks to my 1993 Tannoy Canterbury six months ago, I also addressed this issue because it just annoyed me that it always sounds different depending on how you do it.

So I thought, since I'm not going to do bi amping or bi wiring, maybe it would be best if I avoided it at all. M.a.W. the best possible result without spending money on space rocket jumpers.

This is what it looks like inside the Canterbury speaker now. As I had hoped, it clearly brings the best sound without any preference for mids, lows or highs. Just get rid of what I don't need. So I put bass and treble on just one plug.
