"[edit] Criticism of audiophile marketing practices
Criticisms usually focus on claims around so-called "tweaks" and accessories beyond the core source, amplification, and speaker products. Examples of these accessories include speaker cables, component interconnects, stones, cones, CD markers, and power cables or conditioners.[16] Manufacturers of these products often make strong claims of actual improvement in sound but do not offer any measurements or testable claims. This absence of measurable (rather than subjective) improvement, coupled with sometimes high prices, raises questions about the truthfulness of the marketing.[17]
It is possible to spend over one hundred thousand dollars for a pair of loudspeakers, tens of thousands of dollars for electronics, and more than seven thousand dollars for cables.[18] An example of this type of marketing, and the associated reviews in magazines, is the $1,499 power cord, for which the reviewer states that "The choice of power cord one makes to transmit AC over the final feet to a component has the potential to be the most influential sonic link in a music system's power chain."[19] Another example includes a line with $2,000 power cords.[20]
