Profile: Tara Labs, Inc. offers audio cables. The ZERO series of audio interconnect cables are designed with Rectangular Solid Core® conductors. The RSC® conductors are specially shaped and frequency tuned to reveal more of the harmonic structure of the music than any other audio conductor. These conductors are suspended within a Teflon® tube. The air series 2 series uses frequency-tuned RSC® conductors. The air-tube is a large single Teflon® tube extrusion, with 3 smaller internal tubes extruded in place within the inner walls of the airtube. These 3 internal tubes allow the RSC® conductors to be inserted by hand into air-tube itself with the geometry and electrical characteristics controlled by the spacing of the smaller internal tubes.
