That is what irks me so much, as has done so for many years long before I ever was a cable vendor.  If cables do nothing for the cynics personally then all they have to say ONCE is "I tried XYZ cables and I heard no difference" Job done and let the thread continue unmolested.  Time after time they come barging in uninvited I might add and grind on and on about the same old thing as if it was the very first time it has ever been said   By all means respect others and present a contrary viewpoint without resorting to attacking their personal purchasing choices or wielding irrelevant facts, then you might, just might get some respect in return
