A most unlikely cable convert

OK, here is a BIG win for those who know that different speaker wire sounds different! My dad is an electrical engineer of the 60's ilk. In EVERY sense of the word. You know the type, if it measures better, it is better, solid state measures better than tubes, wire is wire, blah, blah, blah. Of course, my collection of cables engenders reactions that range from ridicule to outright disgust. So tonight he was visiting, and he heard a jazz CD I was playing. Down To The Bone, "From Manhattan To Staten". Great CD, if anyone cares. He was mesmerized, thought it to be the best CD he's heard in years. My system has always drove him to disgust, "Tubes?!?". He couldn't get over how great the system sounded. The fact that he even admitted this after all these years was astounding enough. Then, I suggested the new speaker cables I am using to my mids/tweeters are a very poor match in my system(will be soon taking them out). His answer was, "BS!". So I switched the cables used for the woofers(AudioQuest Midnight) and the ones to the mids/tweeters. Instant difference for the better. And not insignificant. He could not only hear it, HE HAD TO ADMIT IT. So now one of the world's biggest cable naysayers has just become a convert. I hope all who still think "wire is wire" just open their ears the same way my father did tonight.
