AERO-PE
A proprietary dielectric material developed by TARA Labs and used as insulation in most TARA Labs cables.
Dielectric materials sound different because of the different rates that the materials store and release energy at different frequencies. PVC, a common dielectric material, causes distortion and coloration mostly audible in the mid-bass and mid-range frequencies, whereas Teflon® causes distortion in the upper treble frequencies, making coloration less noticeable.
TARA Labs uses a proprietary dielectric material called "Aerospace Polyethylene™" or "Aero-PE™." This material is chemically treated to have low dielectric absorption and high dielectric elasticity. It reacts less with the signal in the conductor, making it more sonically neutral than other materials. Aero-PE is also extruded at a lower temperature than other insulating materials. Copper conductors insulated with Aero-PE are not exposed to high heat and therefore retain their specially annealed qualities.
