A decade after the launch of the original DeMag, Furutech have released a new, improved "Alpha" edition of the now renowned demagnetizer, a massive, luxuriously finished machine with a singular purpose: to discharge the magnetism that resides or builds up in LPs and optical disc media (CD, DVD, SACD, etc), thereby improving their sonic performance. It is equally an indispensable accessory for keeping interconnect cables, connectors and power cords demagnetized to prevent magnetic signal distortion. The Alpha version promises a 20% increase in demagnetization power over the original and, also, features touch panel technology for enhanced ease of use.
As for the question of how a vinyl LP can be magnetized, Furutech explain that the culprit is actually the pigment added to the plastic during the manufacturing process. This pigment contains small amounts of ferrous material which become magnetized as a record spins. The resulting magnetic field has in fact been measured by Tokyo’s Nanotechnology Center, as has the effect of subjecting it to the Furutech DeMag - revealing a clear drop, the company says. The theory behind the benefits of demagnetizing optical media is more widely known. The aluminum used in the reflective surface layer of CDs/DVDs/SACDs also contains ferrous impurities and is thus susceptible to activating a magnetic field. Ditto the ink used in printing the media’s labeling.
As for cables, obviously an electrical current generates a magnetic field as it flows through a power cord or conductor. In addition, impurities within a cable’s materials also become magnetized and introduce further distortion. The solution? According to Furutech, you simply loop your cables with their connectors on the DeMagα and begin treatment.
