Cardas Irrational but Efficacious CD

The main tool is track seven, a five minute glide-tone, that when played through your system at a moderately low listening level, will improve the overall sound presentation of your system.

While we don't have all the technical details of the science involved here at Needle Doctor, we suspect it functions by demagnetizing residual fields that build up in your components over time. We recomend playing this track on a regular basis, anywhere from every two weeks to once a month.
