OK, troll feeding time...
Summer,
I too do not see the reason for your post unless it is simply an advert for Tributaries cable.
And yet, if what you say is true, there should be no reason for Tributaries to exist.
After reading the Tributaries site I do see the many ways they differentiate themselves from those evil people that sell audio cables:
"our products are only based on high quality tried and tested materials and on scientific principles" Ahhh, I see. Those other cable companies that use these mysterious materials (copper, silver, teflon, PVC) don't base their cables on scientific principles.
"bring discernable improvement to any audio or video system by using advanced methods..." But wait, I thought you said this was not possible with wire. I guess the competitors' methods aren't advanced enough to make a difference.
Or maybe it's the radical way they design cables by considering the "...choice of conductors, choice of connectors, impedance stability, cable flexibility, testing..." Damn, the cat's outta the bag now - Other mfgs are surely going to start the consider their choices of conductors and connectors now, and they may even start to test their cables, surely revolutionizing the entire industry!! (Although as you say this makes no difference in the sound. Hmmmmm...)
Or maybe the nylon mesh which "gives the cable an elegant look to compliment your equipment" Now that's surely worth spending extra on, since the other aspects of the cable are irrelevant to their performance.
Or is it the time savings you get when doing digital video editing since the Tributaries coax "ensures a fast lock-on to the digital data stream." Jeez what am I going to do with all that extra time, lemme see...
Or the way their biwire speaker cable "...achieves a sonic advantage resulting in greater high frequency detail and an improved sound stage." Ooops, forgot that wasn't possible. My bad.
OK, I'll stop now.
Let me state that I have absolutely no issue at all with Tributaries cable! (Ironically I was just given a demo pr of spkr cable to try out just yesterday by a dealer after never hearing of the company!) They have a really good web site and they appear to make a quality product.
But isn't it kinda weird that they invoke Gordon Gow's name, and that "The company's philosophical inspiration was the late Gordon J. Gow..." when it is GJG himself that you claim to be the cable myth-buster?

Maybe I see the intent of your post now - It's sort of an "Emperor's New Clothes" thing where the entire premise of your post (GJG has proven that cables make no difference and that there is a company called Tributaries Cables that claims their inspiration for existing to the same GJG) is so totally contradictory that you wanted to see if we'd notice.
I did.
