Controversies
There is substantial controversy on the subject of audiophile components; many have asserted that the occasionally high cost produces no measurable improvement in audio reproduction. For example, skeptic James Randi, through his foundation, has offered a prize of $1 million to anyone who can demonstrate that $7,250 audio cables "are any better than ordinary audio cables". In 2008, audio reviewer Michael Fremer attempted to claim the prize, and said that Randi declined the challenge. Randi said that the cable manufacturer Pear was the one who withdrew.
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.
There is disagreement on how equipment testing should be conducted and as to its utility. Audiophile publications frequently describe differences in quality which are not detected by standard audio system measurements and double blind testing, claiming that music contains elements which cannot be measured by electronic instruments, but without providing an explanation for those claims.
