Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE: Ultimately...

"And it isn't measurable yet. At least not with the tools most of us measure. I'm still thinking about how to do it."

Well, as I've argued, I think it is overwhelmingly more likely that there is no effect there to be measured, and that the difference in sound between the two wire directions is imagined.

However, let us suppose for a moment that you were right, and that there were indeed some significant asymmetry in the wire. Is your idea then that with the wire oriented one way, there is a positive advantage, in comparison to an "ideal" symmetrical wire? Or is your idea instead that an asymmetrical wire is an unfortunate evil, but that with one particular orientation it does less harm to the audio signal than when it has the opposite orientation?

If the latter, then wouldn't that suggest you ought to try the experiment of putting two runs of wire together, with a "positively oriented" wire in parallel with a "negatively oriented" wire? Then, you would eliminate the asymmetry that you believe to be present. Of course you could also achieve a symmetrical arrangement by connecting two equal lengths of wire in series, one oriented oppositely to the other.

So there are two further configurations that you could try out with your listening tests!

Unfortunately, I think the dream that you will uncover deep truths that transcend known physics and electrical engineering by playing around with a home stereo system is just that; a dream. Conceivably you might learn something about human psychology and the way the brain processes its sensory inputs.
