That's fine, you needn't accept the observations of others. Please feel free to conduct your own blind testing, and to share the results with the forum.Just to reiterate what I've already stated, I certainly do perform my own (with the help of an assistant) blind testing in cases where I hear (or believe I do) a difference, in order to confirm/deny my observation.
But in cases where I'm *not* the one making a claim to hear a difference - and wire directionality is one such case - then in my view the onus ought to placed on the person (Geoff) making such claim, not the one (me) disputing it.
