Directional speaker cables - switching direction

Some time ago I started a thread regarding speaker wire directionality and my inability to understand how it could have any affect on sound quality. The question was inspired by the fact that, after quite a few years using them with my Martin Logan Odysseys, I discovered that the cables (Straightwire Octave 2) had arrows printed on them. Not surprisingly the opinions expressed were pretty strong on both sides of the argument but those supporting directionality were the most vociferous and in greater numbers, one to the point of being downright insulting. In no case, though, was an explanation given by those supporting the importance of cable direction for how this phenomenon occurs except that it should be obvious that when a cable is broken in in one direction only someone with an uneducated ear would be unable to discern the difference.

Even though I still don't get it I'm not taking the position that there is no validity to the directional claim; if there truly is I just don't understand how. This leads me to my two part question. I haven't been using the Octaves for a few years but now, because of cable length issues, I want to put them back in my system partly to avoid the cost of new quality cables.

IF, then, the directionality theory IS valid and I don't recall which way the arrows originally pointed or which direction they were "broken in" do those in support of directionality think I should install them with the arrows pointing toward the speakers

It really depends on the individual, hard and fast rules about gender and hearing acuity are not truly "hard and fast". For instance, no female in my family or any girlfriend I have had can hear with the acuity that I can....and I'm male. I've met nobody who has been so annoyed by TV or fluorescent light squeal as I have, to the point of having to leave some stores.

But I have to say in blind tests I have not been able to tell which direction cables are hooked up when I have someone else do the switching (or non-switching).

Audiophiles should read about placebo effect, expectation bias, but of course most audiophiles will be the first to reject such notions, proven as they are.

In many ways, this belief always reminded me of audio:

Keep in mind that this is coming from an audio guy who has been in it for his entire life since 12 years old and who owns a warehouse full of audio gear including hundreds of sets of high end cables. In other words, I'm a big believer in small differences making a big difference. But I've also watched many folks fool themselves and make the wrong pick time and time again, when they swore in advance that they could identify something, when I am the one to make the changes (or not) in what they are listening to.

Different tubes, different companies, active devices, of course there is a difference. And as they break in there is a difference. Real reasons, and not all unmeasureable.

Different cable designs? Absolutely, sound different, measure different, obvious to hear.

Cable direction? Totally different proposition.

I suppose shining lights on the cables makes you hear different resutls, and I suppose after moving them they have to "break in" again.
