This is a poor example of how anyone should conduct tests. The first problem I noticed right away was the "impedance test." This is not how you do this. All he has done is measure the ability of the test instrument to drive this very low complex impedance. You must buffer the test generator from the load.

There are no calculations to show whether or not he is getting the expected results. Why? All the electrical characteristics of each cable are known. It is a critical step that was left out. Deliberate?

There is no list of test equipment used, so recreating this test, done properly or not, is impossible.

There are many more problems with this paper, but I am not going to waste my time with it.

Mr. Pass's test methodology applies the patina of science without actually using any.  Read the conclusion of his report.  It basically says "if you think something helps or is better, use it."  IOW, he's a shill for hyper-priced copper of dubious benefit.

Mr. Pass also did not seem to identify whether the electrical characteristics described in Figure 2 in that article were based on manufacturer specs or actual measurements.   Then again, look at the date on that article as it is almost 32 years old.  The physics associated with cables has not changed since then, however measurement techniques and tools, the electronics commonly involved such as the amplifiers and our understanding of some of the issues involved have evolved over that time.
