cleeds,
You keep raising that question, even though it's been answered a number of times. Here we go again....
You assume people skeptical about boutique cable claims haven't 'done the work.' But note that most of the skepticism comes from the engineering world in which people work with the electrical theories in question. It is from an understanding - theoretical and practical - of how electrical components work that many EEs and other technically qualified skeptics conclude many audiophile claims are bogus. The "work" on electrical theory and cables has essentially "been done."At least, this is a common position of most EE skeptics I've read.
Further, there have been plenty of technically knowledgeable skeptics who HAVE done technical and blind testing of cable claims. Someone has posted quite a few here:

Science oriented web sites like Hydrogen Audio contain plenty of technical tests on audio components, including cables, and blind test results of all sorts of audio components. You can find more technical tests on Audio Science Review, and on Archimego's blog.
More recently, skeptic Ethan Winer has proposed a null test for cable claims...and you can see videos of him showing the results.
I myself have, as I've explained before, blind-tested cables and other devices.
So this objection you continually raise...as if it had any force...just seems ignorant of all the reasons skeptics give for rejecting many of the claims from high end cable companies, and the knowledge, and work, those objections are based upon.
