Michel Plante and Sarah Tremblay of Audiofest Canada, with the support of Kin by Totem (Totem Acoustics), at the Montreal Audiofest, sponsored Audioteens Day on the Sunday of the show, offering free admission to families with teens to expose the young people to high-quality audio. Since Sunday is usually the slowest day of any show, this did not impinge on the audiophile crowd.
They also collected unused older audio gear from members of the industry to be given away in a raffle open to teenagers to help them get started on an audio journey. The raffle was held at the end of the show on Sunday.
Both of these ideas could easily be adopted to attract new people to the high end, as well as stimulate sales of used equipment.
