I used enamelled wire 0.5mm, didn't try bare wire though I should.
One long length doubled back and twisted.
This one long twisted pair then cut into eight lengths and used to construct a pair of interconnects each in star quad configuration.
The connection was straight so I was able to use air spacing with no filler rod or sheathing....these will subtly alter sound signature.

Luckily balanced interconnects are a robust system. Because those DIY interconnects will have more Shield Current Induced Noise (SCID) than a well manufactured Shielded Twisted Pair (STP).

DPH, shut down your computer.
Go to your lounge room and try the experiment of reversing the direction of one of two identical interconnects.
If you do not have a pair of identical interconnects, beg, borrow, steal or construct a pair and try the experiment mentioned.
When you have tried all the permutations of connecting the two interconnects, go back to your computer and report what you find....capisce ?.

Yeah, see, this is exactly what I mean about thorough experiment. I absolutely do not trust myself to be reliable in this test.

But I'm comfortable saying that if it's audible, I'm sure you could do the exact same test with a cleverly designed bridge circuit. Why leave such monumental information about the nature of matter to human ears?

Nope. Not at all. Zero, nein, nada...

Have you guys ever actually done anything remotely close to r&d? Like the kind that has to be reported to other folk and ultimately has translational use to the rest of humanity? (An honest test of does this actually work?) Because if this is all garage "lab" fun and that's all it will remain then anything goes, no matter how wishful it may be. I've done my fair share of dividing by zero, too.

Does this mean you have decided the results without trying it?

Nah, Maxwell did it about 100 years before I was born. Heaviside also contributed to the analysis. For a shift in stereo image there has to be either
1. A time delay
2. A phase shift
3. A belief that something magical is happening.

A phase shift is difficult to make directional for an AC signal. A time delay even harder.

Now you could do a thought experiment that swapping pos and neg for a single ended connection could change things IF there were lower impedance return paths and as this cable being described is a very poor single ended interconnect that might just be possible, and certainly measurable.

Yup. It's for the proponents to prove... Extraordinary claims require extraordinary evidence...

Only a fool believes all that he is told. Another fool might disbelieve all he is told. A wise man believes some of what he is told, so how does he know what to believe and what to ignore? That is what wisdom is about!

Sometime after that a hifi dealer friend showed me the effect of flipping the direction of one interconnect in a clear, revealing system.
Same deal, the balance shifted to one side and balance control did not cure the problem.....the penny dropped, this was the problem with my TT.

As soon as I got home I reversed the direction of one of the TT phono cables and presto, problem solved....at last !.

Ah, that must be it: none of us has a "clear, revealing system".

The root of the problem was that I listened to the answer that I was given when I asked in class if wires are directional....the answer was an emphatic "NO, wires are not and cannot be directional".....because of this belief I did not pay attention to ensuring that both channel cables laid in the same direction.

'Audio wires are not directional' is not a "belief", it is a fact. It would have been better to ask "why are audio cables not directional?", then you would have understanding.

So I am over at a friends house in the neighborhood. All of the homes are the same layout/floor plan as they were built by the same builder.
We have the exact same sound system, everything, amps, speakers, cables, etc. I play a piece of music that I really like and know how it sounds on my system on his and wow what a difference. As we talk about it, we realize my house is oriented north to south and his is east to west.
Who would have thought just a ninety degree change would make such a difference in the sound. Wow!!
