Copper Wire Cotton Insulation

Solid Core Copper Wire Cotton Insulation Spool

Jupiter wire products are all of high purity metals with natural cotton or silk insulation. Plastic insulation and coatings can have strained or glaring sonic attributes which are unnatural to the ear. Cotton and Silk insulation act as a fibrous 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.
