Abstract
An audio cable is cryogenically treated in a cryogenic chamber. The cable is disposed within the cryogenic chamber. A temperature in the cryogenic chamber decreases to a level between −157° C. and −184° C. over 12 hours of the cryogenic treatment profile. The temperature in the cryogenic chamber is held steady state at the level for 8-12 hours. The temperature in the cryogenic chamber increases back to an ambient temperature over 8 hours. A computer control system controls the temperature in the cryogenic chamber by regulating nitrogen gas flow into the cryogenic chamber. The temperature in the cryogenic chamber can be decreased in a first stepped profile, and then increased in a second stepped profile. Alternatively, a bare conductor is disposed within the cryogenic chamber. The bare conductor is cryogenically treated and then used in another device, such as cable, magnetic pickup, speaker voice coil, microphone, and instrument string.
