How would that make any difference to audio frequencies ? The coil is an inductor with a certain resistance, those parameters do not change It's orientation makes no difference to these parameters. You need to get a life.
Clearly you think that a capacitors orientation somehow affects the way it either blocks DC or passes audio frequencies, and that this difference is audible, and you provide no explanation why.
Well I am easily able to change the orientation of my single Polypropolene capacitor in the crossover to my tweeter, it makes absolutely no difference to the sound that I can hear even when I know the orientation, and I doubt that you would ever hear a difference in a blind test either.
I'm guessing you spend a lot of money on your interconnects and speaker cables ?
I think a South African friend of mine, an earnest Greek, and a rather well-known designer in Berkeley have to be rolling on the floor right now.
I make no claim that lead reversal effects are universally or commonly an audio issue. But they are within the scope of physical possibility and (especially with inductors) every experienced designer has a story of an oddball problem.

No, I will do your test exactly like you've described. The only reason for my post was that I've done a similar test before.
"Similar" except for the controls. Seriously. You can't cut corners there; using your son, direct interaction with the person doing the switching during the course of the test, no independently held key sheet and score sheet, all that takes it completely out of the controlled sensory test realm.

This must be the funniest thing i've ever read on a forum. SY, let this be a lesson to you 🙂

mwaters10, I've said it is possible that the polarity can have an influence, I've never tested it because it is easy enough to connect them the better way, just for incase. 😉 It surely would not hurt to connect the outer foil to the low impedance side and benefit from the screen effect also.
If you can't hear a difference, it doesn't count for much, you can't even hear differences between cables. 😀 😀 😀

Why couldn't we just take some interconnects and run Audio Rightmark through them? It takes a picture of the entire output/input chain but still if there is a signifigant difference between interconnect to interconnect there should be a signifigant difference in the test results right? I mean that is the easist thing I can think of beyond subjective listening tests.
You contradict yourself. The description you gave was
"the influence of fields and strays will be different"
You actually allow this notion to make you orientate your film capacitors in a particular direction, but I don't think you even understand why you are doing this. You haven't claimed to hear a difference, as yet. Do you ?
So what is the point of even making such a statement.
All it does is mislead others into wasting time on things that are pointless.

I understand what you say and will do it like that.
Just for interest, my son is quite young and did not know what I was testing, I just told him to insert the IC's with the writing to either side, corresponding to the table he made by flipping a coin.
analog-sa, you have to be wetting your pants about now. Someone tell Curl to look at this, he could use a good laugh. Hansen, too. Oh, this is rich.
Non polarised capacitors are exactly that, you think that the AC frequency gives a s**t which way a non polarised capacitor is orientated ?
So what .. if a single ended metallised electode in a film capacitor is facing ground.
By all means, have a good laugh, but this is why audiofools are such idiots.

Seriously, try looking at the actual physical construction of real metal-and-plastic components. Then think about Maxwell's equations. Ideal models are models. Real components don't behave that way in all circumstances.
Bob Pease's book on analog troubleshooting ought to be on your bookshelf.

If you don't care for the detail, don't expect to hear it. 😉
FFS,
coils with polarity ..
non polarised capactors with polarity
When did you ever hear that a non-polarised capacitor must be placed in a particular orientation.
Screw the fact that your designer mate is from Berkeley, that doesn't mean that you know what you are talking about.
Maybe, capacitor manufacturers ought to re-write all their
datasheets, just for audiofools.

Living without switches of some sort is not very practical. Occasionally a single source lashup with no switches does happen around here.
I'm not saying a switch (and extra connectors) can't be used in such a test, just that one would need to show that they don't confound the test.

Eh I figured no one would take me up on my idea so I went ahead and did it with what I have. So Switchcraft vs Radioshack 1/4" TRS balanced. One is shielded (switchcraft) and one is just rubber shielding and whatever they have under that rubber (radioshack).
Also tried radioshack 1/4" TS unbalanced but I actually don't have 2 "decent" matched 1/4" TS to put them up against so you get one "gold tipped" fender on the left channel and one heavily shielded DiMarzio on the right channel.
This is the most retarded controlled test ever haha but I don't give a ____ I am just trying to find out something a little more simple than what causes differences in cables. I am trying to find out if the difference in various cables makes any significant difference. Much much simpler to find out than the specifics imo.
