I thought this stuff might be sold for nostalgia restoration projects, but one vendor has this bullshit-
Jupiter wire products are all of high purity metals with natural cotton or silk insulation. Plastic insulation and coatings can have strained or glari ng sonic attributes which are unnatural to the ear. Cotton and Silk insulat ion acts as a ?brous matrix for separating wires while maintaining a predominantly air dielectric, sonically very natural and open. So many of the modern innovations do not translate to better or more natural sound.
