Interesting article on measuring speaker cables, are high priced cables bogus, or not? The bogus websites deny, deny, deny that cables matter, offer them proof and they deny, deny, deny the very "measurements" they claim to embrace.
ABSTRACT
This paper describes a simple experiment to identify the performance of a number of different speaker cables by measuring the “error” introduced into an audio system by each cable, i.e., the voltage drop between the amplifier and the speaker. The signals used are both white noise (https://en.wikipedia.org/wiki/White_noise) and music.
The results show that the principal factor determining the error of a cable is its geometry. Cables with very widely spaced conductors have the greatest error, closer-spaced conductor cables have less error, and very closely-spaced, flat conductor cables have the least, or near zero error. [Townshend Audio’s Isolda speaker cable is such a design. – Ed.] The results have been presented both visually and sonically at https://youtu.be/v11hmOE1Vcc.
The experimental method has been described in detail, to enable researchers to repeat the tests in order to verify the conclusions. The results of this experiment may embarrass those cable sound deniers who have hindered the advance of hi-fi for the past 50 years, and hence may allow the quality of high-fidelity sound reproduction to advance.
