Cable Pathways Between Audio Components Can Affect Perceived Sound Quality
Cable Pathways Between Audio Components Can Affect Perceived Sound Quality
This work shows that two system configurations differing only by the interconnect pathway are audibly discernable even by average listeners with no special experience in music or audio. To the author’s knowl- edge this may represent the smallest change in an audio sys- tem proven to be discernable through IRB-approved blind listening tests.

This work did not conduct an exhaustive determination of all possible physical causes of sonic differences in intercon- nects. For example time-domain effects such as reflections were not studied because a balanced cable requires a dif- ferential amplifier and extra cable (both adding their own noise and distortions) before an oscilloscope.
