In truth, and I'm not saying that directionality does exist, it is not beneficial, for someone involved in a technical business like Hi-Fi, to make claims and then admit you don't know why or how this thing happens. In reality the guy is admitting he does not know, but that it does occur because he himself observes it. This is brave and I personally would not poo-poo him for putting his head on the block. Is it not more likely that RA will loose credibility for speaking openly of this, if he was totally business orientated I think he would have kept his mouth shut. I will continue to look into this and await the arrival of my Ben Duncan book which claims to prove cable directionality. Wish me luck.
