Okay, so I looked and looked to try and find some reference as to who Barish is or what he has accomplished and I can't find a thing. That's not to say that he doesn't know a lot about music. But, honestly, if he is as accomplished as you say he is, he should easily be able to recognize the need for a FIRST HAND demonstration.
I have had this discussion many times on several forums and even more often in person. I have never convinced anyone that there was a difference without taking them to my studio and showing them the difference. But surely I'm being silly... why would you ever believe your ears when you can endlessly debate the topic online?
I guess if you guys really want, I can mic one of my S3A monitors and record a sample with the standard IEC and again with the Shunyata cable... Then we can start a whole other discussion as to weather the mic was at the exact same angle, and weather or not the microwave was running when I ran the test...
Seriously, JUST DEMO THEM. A list of world distributers:

Also, here is a list of ignorant dafties who all agree that iec cables do matter:
