I was only trying to focus on the theory 'apart from fact' in an effort to get a sense of what is in the minds of those who believe things like wire directionality might be real....or maybe I should say 'theory "apart from established fact"...or is it "apart from already established fact"??....or "the most familiar already established universally accepted fact"???....or whatever level of truth needs to be met - sometimes that makes my head hurt.
I myself have heard the directionality effect a few times over the last few years. Sometimes I've heard it when I didn't expect to. Sometimes I didn't hear it when I was expecting to. But, when on those (few) occasions that I did repeatedly hear it, most often I heard it a little more plainly with fuses than with wire in my setup.
Oddly, I can no longer hear the effect under my roof. I've been steadily acquiring more and more electronic noise reduction gear (quantum based) from Alan Maher Designs since coming across that site in 2010. Slowly since then the effect has started growing noticeably weaker as my system improved in sound and performance. Now I can switch out seemingly any wire or fuse and even while hearing an improvement or at least change in sound vs the original wire or fuse, I no longer can audibly detect any delta from directionality, no matter what the test. As if the rest of my system's performance has improved to the point as to 'swallow up' the differences, perhaps??...not really sure... I do know all the "hifi-ness" is gone...almost as if directionality and hifi-ness were somehow being 'bouyed up by electrical noise' as it were.
I can't explain or account for why that would be the case, I just know that it is.
