It says a lot about it. Which specific parts are you referring to? It's mainly about speaker wire gauges and how that affects sound etc. there's a lot about audible and inaudible differences.
Did you see this part? And did you take note of Roger Russell's resume?
The Big Picture
There is big money to be made in wire, not only speaker wire but all kinds of exotic wire—hookup wire, audio cables, power cables and a wide variety of speaker wire including the new term of “speaker cables.” The term cable implies more robust and heavy duty qualities than wire.
I have learned from one wire company that much of this exotic wire is not manufactured in the USA at all. It comes from places like Taiwan and China. It can be bought in industrial quantities at surprisingly little cost and sold for tremendous profits. Custom runs in large quantities, can be purchased having any number of different features and are not a problem for versatile wire manufacturers. It can even be made with various terminals already installed.
The strategy in selling these products is, in part, to appeal to those who are looking to impress others with something unique and expensive. There is also pride of ownership and the belief that if it costs that much it must be good. It reminds me of the Percy Bysshe Shelley poem
Ozymandias but for speaker wire it translates to “Look upon my expensive wires ye mighty and despair.” It will always sell to those who want the latest thing and would spend as much for a Rolex watch as they would for wire. Of course, there are ordinary watches that will tell time accurately they but don’t have that name or that price.
Another part of the strategy is to capitalize on the lack of truth in advertising, particularly the whole truth. Perhaps the two words “truth” and “advertising” are on opposite extremes but half of the truth can be worse than a lie. I don’t think the average consumer is any match to cope with the persuasive sales “hype” of professional salesmen praising a questionable wire science and doubtful benefits.
When confronted with the truth, believers do not want to hear about it. They want to remain in the magical world of fantasy where they think they can hear improvements in their wire, often arrived at by making listening tests without adequate controls or understanding of the problems involved including speaker impedance and amplifier stability. One of the prime tools in creating such a faith for the average consumer is by capitalizing on fear and ignorance as in many other things that aren’t readily apparent. There is fear that the wire currently in use is not good enough. There is ignorance because most people do not have scientific knowledge in this area and lack adequate measuring equipment to prove otherwise.
