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 One Million Dollar Paranormal Challenge, 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 Cables was the one who withdrew.
